RECOMMENDATIONS. - Yale College, Nov. 27, 1790. I have read Daboli's SchoolMaster's Assistant. The arrangement of the different branches of Arithmetic is judicious and perspicuous. The author has well ex- plained Decimal Arithmetic, and has applied it in a plain and elegant manner in the solution of various questions, and especially to those relative to the Federal Computation of money. I think it will be a very useful book to School- masters and their pupils. JOSIAH MEIGS, Professor of Mathematics and Natural Philosophy. [Now Surveyor-General of the United States.] ! have given some attention to the work above men- ºtiºned, and concur with Mr. Professor Meigs in his opinion ºf its merit. NOAH WEESTER. New-Haven Dec. 12, 1799. - Rhode-Island College, Nov.30, 1799. I have run through Mr. Dabout.’s SchoolMaster's Assistant, and have formed of it a very favourable opinion. According to its original design, I think it well “calculated to furnish Schools in general with a methodical, easy, and comprehensive System of Practical Arithmetic.” I there- fore hope it may find a generous patronage, and have an ºxtensive spread.

JOHN ADAMS, Rector of Plainfield Academy. [Now Principal of Philips' Academy, Andover, Mass.] - Billerica Academy, (Mass.) Dec. 10, 1807. Having examined Mr. Danoll’s System of Arithmetic, I am pleased with the judgment displayed in his method, and the perspicuity of his explanations, and thinking it as easy and comprehensive a system as any with which I am acquainted, can cheerfully recommend it to the patronage ºf Instructºrs. SAMUEL WHITING, Teacher of Mathematics. - fºrum Mr. Kennedy, Teacher of Mathematics. 1 became acquainted with Damodt's SchoolMaster's As ustant, in the year 1802, and on examining it atten- tively, gave it my decisive preference to any other system extant, and immediately adopted it for the pupils under my harge; and since that time have used it exclusively in elementary tuition, to the ſº advantage and improve- ºnent of the student, as well as the ease and assistance of he preceptor. I also deem it equally well calculated for the benefit of individuals in private instruction; and think it my duty to give the labour and ingenuity of the author the tribute of my hearty approval and recommendation. ROGER KENNEDY New-York, March 20 1811. PIR. E. F.A.C.E. . . - The design of this work is to furnish the schools of the lºnited States with a methodical and comprehensive system of Practical Arithmetic, in which I have endeavoured, through the whole, to have the rules as concise and fami- liar as the nature of the subject will permit. During the long period which I have devoted to the in- struction of youth in Arithmetic, I have made use of various systems which have just claims to scientific merit; but the authors appear to have been deficient in an important point—the practical teacher's experience. They have been too spuring of examples, especially in the first rudiments; in consequence of which, the young pupil is hurried through the ground rules too fast for his capacity. This objection I have endeavoured to obviate in the following treatise. In teaching the first rules, I have found it best to en- tourage the attention of scholars by a variety of easy and familiar questions, which might serve to strengthen their minds as their studies grew more arduous. The rules are arranged in such order as to introduce the most simple and necessary parts, previous to those which are more abstruse and difficult. To enter into a detail of the whole work would be te- duous; I shall therefore notice only a few particulars, and refer the reader to the contents. Although the Federal Coin is purely decimal, it is so nearly allied to whole numbers, and so absolutely necessary to be understood by every one, that I have introduced it immediately after addition of whole numbers, and also shown how to find the value of goods therein, immediately after simple multiplication; which may be of great advan- tage to many, who perhaps will not have an opportunity of learning fractions. In the arrangement of fractions, I have taken ºr tº: new method, the advantages and facility ºf wºr" ºf **iciently apºlogize f its not heing w riºt a rº a 2 -- ºn------ systems. As decimal fructions may be learned much eashes than vulgar, and are more simple, useful, and necessary, and soonest wanted in more useful branches of Arithmetic, they ought to be learned first, and Vulgar Fractions omitted, until further progress in the science shall make them ne- cessary. It may be well to obtain a general idea of them, and to attend to two or three easy problems therein; after which, the scholar may learn decimals, which will be ne- cessary in the reduction of currencies, computing interest, and many other branches. Besides, to obtain a thorough knowledge of Vulgar Frac. tions, is generally a task too hard for young scholars who have made no further progress in Arithmetic than Reduc. tion, and often discourages them. I have therefore placed a few problems in Fractions, ac cording to the method above hinted; and after going through the principal mercantile rules have treated upon Vulga Fractions at large, the scholar being now capable of going through them with advantage and ease. In Simple Interest, in Federal Money, I have given seve- rul new and concise rules; some of which are particularly designed for the use of the compting-house. The Appendir contains a variety of rules for casting Interest, Rebate, &c. together with a number of the most easy and useful problems, for measuring superficies and solids, examples of forms commonly used in transacting business, useful tables, &c. which are designed as aids ir the common business of life. Perfect accuracy, in a work of this nature, can hardly be expected; errors of the press, or perhaps of the author may have escaped correction. If any such are pointer ºut, it will be considered as a mark of friendship and ſº tour, by The public's most humble and obedient Servant, MATHAN DABOLL. - - - annition, simple, - - - - - - - - 17 - of Federal Money, - - - - - - -1 - Compound, - - - - - - - 33 Alligation, - - - - - - - - - 177 Annuities or Pensions, at Compound Interest, - - - 19- Arithmetical Progression, - - - - - - 182 Barter, - - - - - - - - - - 126 Brokerage, - - - - - - - - 113 Characters.

Explanation of Characters used in this Book. - = Equal to, as 12d. = 1s, signifies that 12 pence are equal to 1 shilling. + More, the sign of Addition; as, 5+7=12, signifies that 5 and 7 added together, are equal to 12. – Minus, or less, the sign of Subtraction; as, 6–2=4, sig- nifies that 2 subtracted from 6, leaves 4. × Multiply, or with, the sign of Multiplication; as, 4×3=12, signifies that 4 multiplied by 3, is equal to 12. + The sign of Division; as, 8+2=4, signifies that 8 diº vided by 2, is equal to 4; or thus, 3–4, each of which signify the same thing. * : Four points set in the middle of four numbers, denote them to be proportional to one another, by the rule of three; as 2:4:: 8: 16; that is, as 2 to 4, so is 8 to 16. v. Prefixed to any number, supposes that the square root of that number is required. */ Prefixed to any number, supposes the cube root of that number is required. v Denotes the biquadrate root, or fourth power, &c. ARITHMETIC, ARITHMETIC is the art of computing by numbers, and has five principal rules for its operation, viz. Numera- tion, Addition, Subtraction, Multiplication, and Division. NUMERATION. Numeration is the art of numbering. It teaches to ex- press the value of any proposed number by the following characters, or figures: -1, 2, 3, 4, 5, 6, 7, 8, 9, 0–or cipher. Besides the simple value of figures, each has a local ralue, which depend upon the place it stands in, viz. any igure in the place of units, represents only its simple value, or so many ones; but in the second place, or place oftens, it becomes so many tens, or ten times its simple value; and in the third place, or place of hundreds, it becomes a hundred times its simple value, and soon, as in the following Nºte:-Although a cipher standiº alone signiſes nothing; yet when it is placed on the right hard uſ figures, it increases their value in a tenſold prºportion, by throwing them into higher places. Thus, 2 with a cipheran- nexed tº it, becomes 20, twenty, and with twº ciphers, thus, 200,two hundred. º: when numbers consisting of many figures, are given to be read, it will be ſound convenient to divide them into as many periods as we can, of six figures each, reckoning from the riºt hand towards the leſ, calling the ºr-tº- riod of units, the secºnd that of millions, the third billions, the four-n trillions, &c. as in the following number: 5 D7 - 5 - 5 - 5 - 7 - 9 0 1 2 5 0 g º q + 4.

This is the most simple and easy of all money—it in creases in a tenfold proportion, like whole numbers. 10 mills, (m.) make 1 cent, marked t- 10 rººts, I dine, d. 10 lºes, I dollar, 3. E. 10 ars, I engº, addition or PEDERAL MONEY. 2. Dollar is the money unit; all other denominations being ralued according to their place from the dollar's place- A point or comma, called a separatriz, may be placed after the dollars to separate them from the inferior denominations; then the first figure at the right of this separatrix is dimes, the second figure cents, and the third mills." ADDITION OF FEDERAL MONEY. Rule.-1. Place the numbers according to their value; that is, dollars under dollars, dimes under dimes, conts under cents, &c. and proceed exactly as in whole numbers; then place the separatrix in the sum total, directly under the separating points above. examples. -º-d. c. m. $. d. c. m. $. d. c. m. 365, 5 4 1 439, 3 0-4 136, 5 I 4 487, 0-6-0 416, 3-9 0 125, 0 90 94, 6-7 9 168, 9 3-4 200, 9 0-9 439, 0 & 9 239, 0-6 0 304, 0-0 6 742, 5-0 0 143, 0-0 5. 111, 19 1 212°, 8 G 0 2. When accounts are kept in dollars and cents, and no other de- ominations are mentioned, which is the usual mode in common reck- -ning, then the first two figures at the right of the separatrix or point, any be called so many cents instead of dinnes and cents : for the lace of dinºsis only the ten's place in cents; because ten cents make a dime; for example, 48.75, forty-eight dollars, seven dimes, five cents, may be read forty-eight dollars and seventy-five cente.

SIMPLE DIVISION teaches to find how many time. one whole number is contained in another ; and also wha remains; and is a concise way of performing several sub tractions. Four principal parts are to be noticed in Division: 1. The Dividend, or number given to be divided. 2. The Divisor, or number given to divide by. 3. The Quotient, or answer to the question, which shows how many times the divisor is contained in the dividend. 4. The Remainder, which is always less than the divisor and of the same name with the Dividend. to-vision or wildle NUM-ERs. 33 Rºle.—First, seek how many times the divisor is contained in as many of the left hand figures of the dividend as are just necessary : (that is, find the greatest figure that the divisor can be multiplied by, so as to produce a product that shall not exceed the part of the divi- send used:) when found, place the figure in the quotient; multiply the divisor by this quotient figure; place the product under that part ºf the dividend used; then subtract it therefrom, and bring down the next figure of the dividend to the right hand of the remainder; after which, you must seek, multiply and subtract, till you have brought down every figure of the dividend. Paoor. Multiply the divisor and quotient together, and and the emainder, if there be any, to the product; if the work be right, the sum will be equal to the dividend.” Ex-MPLEs. 1.

Add the remainder and all the products of the several quotient figures multiplied by the divisor together, according to the order in which they stand in the work; and this sum, when the work is right, will be equal to the dividend. A third method of proof by excess of nines is as follows, viz. 1. Cast the nines out of tre divisor, and place the excess on the left hand. 2. Do the same with the quotient, and place it on the right hand. 3. Multiply these two figures toºether, and add their product to the re- mainder, and reject the nines, and place the excess attop. 4.

Tuns, hundreds, quar- ters, &c. Rule.—1. Place the numbers so that those of the same denomina tion may stand directly under each other. 2. Add the first column or denomination together, as in whole num bers; then divide the sum by as many of the same denomination as make one of the next greater; setting down the remainder under the column added, and carry the quotient to the next superior denomina tion, continuing the same to the last, which add, as in simple addition." 1. STERLING MONEY, Is the money of accountin Great-Britain, and is reckon- ed in Pounds, Shillings, Pence and Farthings. See the Pence Tables. - - The reason of this rule is evident: For, addition of this money, as 1 in the pence is equal to 4 in the farthingº.1 in the shillings, to 12 in the pence; and 1 in * pounds, to 20 in the shillings; therefore carrying as di rected, is the arranging the monº arising from each column, properly in the scale of denominations: and this reasoning will hold good in the ad. diuono compound numbers of any denomination whatever, co-Poux D Ann-Tion. ---------- C. s. d.

COMPOUND SUBTRACTION, TEACHES to find the difference, inequality, or excess, between any two sums of diverse denominations. -- Rule.-Place those numbers under each other, which are of the same denomination, the less being below the greater; begin with the least denomination, and if it exceed the figure over it, borrow as many units as make one of the next greater; subtract it therefrom; and to the difference add the upper figure, remembering always to add one to the next superior denomination for that which you borrowed.

Ascending, is when small names are brought into great, is shillings into pounds, hours into days, &c. This is per- ºrmed by Division. REDUCTION DESCENDING. Rule-Multiply the highest denomination ºven by so many of -- nºt lºss as make one of that greater, and thus continue till you ave brought it down as low as your question requires. Proof. Change the order of the question, and divide your last ºduct by the last multiplier, and so on. Ex-M-LEs. I.

WULGAR AND DECIMAL. A Vulgar Fraction, is represented by two numbers placed one above another, with a line drawn between them, thus, &c. signifies three fourths, five eighths, &c. The figure above the line, is called the numerator, and at below it, the denominator; 5 Numerator. Thus, | - s Denominator. The denominator (which is the divisor in division) shows how many parts the integer is divided into; and the nume rator (which is the remainder after division) shows howma ny of those parts are meant by the fraction. A fraction is said to be in its least or lowest terms, when it is expressed by the least numbers possible, as : when re- duced to its lowest terms will be 1, and ºr is equal to 1, &c. ------------- To abbreviate or reduce fractions to their lowest terms. Rule.-Divide the terms of the given fºrtion by any number which will divide them without a remainder, and the quotients again in the ame manner; and so on, till it appears that there is no number greatºr than 1, which will divide them, and the fraction will be in its --torns.

A Decimal *raction is that whose denominator is a unit, with a cipher, or ciphers annexed to it, Thus, , , , , , , , º, &c. &c. 72 -na-TION-- The integer is always divided either into 10, 100, 1000 &c. equal parts; consequently the denominator of the frac tion will always be either 10, 100, 1000, or 10000, &c. which being understood, need not be expressed; for the true value of the fraction may be expressed by writing the numerator only with a point before it on the left hand thus, ºr is writ- ten ,5; ºr ,45; Fºr ,725, &c. But if the numerator has not so many places as the de- nominator has ciphers, put so many ciphers before it, viz. at the left hand, as will make up the defect; so write rº, thus, ,05; and rººm thus, ,006, &c. Note. The point prefixed is called the separatrix. Decimals are counted from the left towards the right hand, and each figure takes its value by its distance from the unit's place; if it be in the first place after units, (orse- parating point) it signifies tenths; if in the second, hun dredths, &c. decreasing in each place in a tenfold propor tion, as in the following NUMERATION T-a-º. * * + º- - - - 3 : * = - - - - - - * ºf E = 3 E E = . ##### - * ºr . #2 = E = 5. º, º - - = E = E = - * = E = nº E-TF = 3 - = E = 5 & 5 : E = 3 - - - +E → -- - =F = E = #3 # E = − == - : , ; F = ~...~ - - - - * - 7 6 5 4 3 2 1 2 3 4 5 6 7 Whole numbers.

Ciphers placed at the right hand of a decimal fraction do not alter its value, since every significant figure conti- nues to possess the same place: so ,5,50 and 500 are all the same value, and equal to ſº, or . But ciphers placed at the left hand of decimals, decrease their value in a tenfold proportion, by removing them fur- ther from the decimal point. Thus, 5 ,05 ,005, &c. are five tenth parts, five hundredth parts, five thousandth parts. &c. respectively. It is therefore evident that the magnitude DE-1-1AL FRACTIONs. - 73 of a decimal fraction, compared with another, does not de end upon the number of its figures, but upon the value of its first left hand figure: for instance, a fraction beginnin with any figure less than 9 such as 899.229, &c. if .# ed to an infinite number of figures, will not equal 9. ADDITION OF DECIMALS. Rule-1, Place the numbers, whether mixed or pure decimals, un- wer each other, according to the value of their places. 2. Find their sum as in whole numbers, and point off so many places or the decimals, as are equal to the greatest number of decimal parts in any of the given numbers. - ---------- 1.

Or, it is 103 units, and 3 tenth parts, 1 hundredth part, and 2 thousandth parts of a unit, or 1. Hence we may observe, that decimals, and FEDERAL Moxey, are subject to one and the same law of notation, and consequently of operation. For since º is the money unit; and a dime being the tenth, a cent the hundredth, and a mill the thousandth º of a dollar, or unit, it is evident that any number of ollars, dimes, cents and mills, is simply the expression of jollars, and decimal parts of a dollar.

THE Rule of Three Direct teaches, by having three numbers given to find a fourth, which shall have the same proportion to the third, as the second has to the first. 1. Observe that two of the given numbers in your ques- tion are always of the same name or kind; one of which must be the first number in stating, and the other the third number; consequently the first and third numbers must al ways be of the same name, or kind; and the other number, which is of the same kind with the answer, or thing sought, will always possess the second or middle place. 2. The third term is a demand; and may be known by these or the like words before it, viz. What will? What cost! How many? How far? How long? or, How much? &c. RULE or Tunes D1- CT. al- Rule.-1. State the question; that is, place the numbers so that the first and third terms may be of the same kind; and the second term of the same kind with the answer, or thing sought. 2. Bring the first and third terms to the same denomination, and educe the second term to the lowest name mentioned in it. 3. Multiply the second and third terms together, and divide their product by the first term; and the quotient will be the answer to the question, in the same denomination you left the second term in, which may be brought into any other denomination required. The method of proof is by inverting the question. [NOTE.-The following methods of operation, when they can be used, perform the work in a much shorter manner than the Aeneral rule. 1. Divide the second term by the first; multiply the quotient into the third, and the product will be the answer. Ör, 2. Divide the third term by the first; multiply the quotientinto the second, and the product will be the answer. Or, 3. Divide the first term by the second, and the third by that quotient, and the last quotient will be the answer: , or, 4. Divide the first term by the third, and the second by that quotient, and the last quotient will be the answer.] Ex-A-Lºs. 1.

THE Rule of Three Inverse, teaches by having three numbers given to find a fourth, which shall have the same proportion to the second, as the first has to the third. If more requires more, or less requires less, the question belongs to the Rule of Three Direct. But if more requires less, or less requires more, the ques- tion belongs to the Rule of Three Inverse; which may al- ways be known from the nature and tenor of the question. For example: º RULE ºr tº R-E-Nº-Erase If 2 men can mow a field in 4 days, how many days will it require 4 men to mow it? --- da --- 1. If 2 require how much time will 4 require 1 Answer, 2 days. Here more requires less, viz. the more men the less time is required. ºn-ºn- days --- 2. If 4 require 2 how much time will 2 require? Answer, 4 days. Here less requires more, viz. the less the number of men are, the more days are required—therefore the question belongs to Inverse Proportion. Rule.-1. State and reduce the terms as in the Rule of Three Di- rect. 2. Multiply the first and second terms together, and divide the pro- duct by the third; the quotient will be the answer in the same deno. ºuination as the middle term was reduced into. Ex-------- 1.

PRACTICE is a contraction of the Rule of Three Direc. when the first term happens to be a unit or one, and is a concise method of resolving most questions that occur in trade or business where money is reckoned in pounds, shil- ings and pence; but reckoning in federal money will ren- der this rule almost useless: for which reason I shall no ºnlarge so much on the subject as many other writers have done.

TARE AND TRET. TARE and Tret are practical rules for deducting cer- tain allowances which are made by merchants, in buying and selling goods, &c. by weight; in which are noticed the following particulars: 1. Gross Weight, which is the whole weight of any sort of goods, together with the box, cask, or bag, &c. which contains them. 2. Tare, which is an allowance made to the buyer, for the weight of the box, cask, or bag, &c. which contains the goods bought, and is either at so much per box, &c. or at ºr much per cwt. or at so much in the whole gross weight. 104 TARE ANL TRET. 3. Tret, which is an allowance of 4 lb. on every 104 m. for waste, dust, &c. 4. Cloff, which is an allowance made of 2 lb. upon every 3 cwt. 5. Suttle, is what remains after one or two allowances have been deducted. CASE I.

Simple Interest is the sum paid by the borrower to the lender for the use of money lent; and is generally at a cer- tain rate per cent. per annum, which in several of the Uni- ted States is fixed by law at 6 percent. per annum; that is, 6l. for the use of 100l. or 6 dollars for the use of 100 dol lars for one year, &c. Principal, is the sum lent. Rate, is the sum per cent. agreed on. Amrºt is the principal and interest added together. CASE 1. To find the interest of any given sum for one year. Rule.—Multiply the principal by the rate per cent. and divide the product by 100; the quotient will be the answer. Ex-ML-L--- 1.

Ans, ºn 12 tº run ------ LAT-Mº, NTE-F-T. I-1 Note:-The preceding Rule, by custom, is rendered so popular, and so much practised and esteemed by many on ºccount of its being simple and concise, that I have given it a place: it may answer for short periods of time, but in a long course of years, it will be found to be very errone- ----- - Although this method seems at first view to be upon the ground of simple interest, yet upon a little attention the following objection will be found most clearly to lie against it, viz. that the interest will, in a course of years, complete- ly expunge, or as it may be said, eat up the debt. For an explanation of this, take the following -------- A lends B 100 dollars, at 6 per cent. interest, and takes His note of hand; B does no more than pay A at every rear's end 6 dollars, (which is then justly due to B for the *se of his money) and has it endorsed on his note. At the and of 10 years B takes up his note, and the sum he has to lay is reckoned thus: The principal 100 dollars, on inte rest 10 years amounts to 160 dollars; there are nine en- dorsements of 6 dollars each, upon which the debtor claims interest; one for nine years, the second for 8 years, the third for 7 years, and so down to the time of settlement; the whole amount of the several endorsements and their in- terest, (as any one can see by casting it) is $70, 20cts, this subtracted from 160 dols, the amount of the debt, leaves in favour of the creditor, $89, 40 cts. or 810, 20cts, less than the original principal, of which he has not received a cent, but only its annual interest. If the same note should lie 20 years in the same way, B would owe but 37 dols. 60 cts, without paying the least fraction of the 100 dollars borrowed. Extend it to 28 years, and A the creditor would fall in debt to B, without receiving a cent of the 100 dols, which he lent him. See a better Rule in Simple Interest by de- timals, page 175. - 22 -------------------T COMPOUND INTEREST, 1S when the interest is added to the principal, at the end of the year, and on that amont the interest cast for ano- ther year, and added again, and so on: this is called inte- rest upon interest. Rule.—Find the interest for a year, and add it to the princi- pal, which call the amount for the first year; find the interest of this amount, which add as before, for the amount of the se- cond, and so on for any number of years required. Subtract the original principal from the last amount, and the remainder will be the Compound Interest for the whole time. ----------- 1.

When the debtor keeps the annuity in his own hands beyond the time of payment, it is said to be in arrears. The sum of all the annuities for the time they have been foreborne, together with the interest due on each, is called the amount.

DOLIBLE IRULE OF THREE. THE Double Rule of Three teaches to resolve at once such questions as require two or more statings in simple proportion, whether director inverse. In this rule there are always five terms given to find a sixth; the first three terms of which are a supposition, the last two a demand. Rule.—in stating the question, place the terms of the supposi tion so that the principal cause of loss, gain, or action, possess the first place; that which signifies time, distance of place, &c. in the second place; and the remaining term in the third place. Place the terms of demand, under those of the same kind-in the supposition. If the blank place, or term sought, fall un- der the third term, the proportion is direct; then multiply the first and second terms together for a divisor, and the other thren for a dividend - but if the blank fall under the first or second term, the proportion is inverse; then multiply the third-and fourth terms together for a divisor, and the other three for a di vidend, and the quotient will be the answer.

HAVING briefly introduced Vulgar Fractions imme- diately after reduction of whole numbers, and given some general definitions, and a few such problems therein as were necessary to prepare and lead the scholar immediate- ly to decimals; the learner is therefore requested to read those general definitions in page 69. Vulgar Fractions are either proper, improper, single, compound, or mixed. 1. A single, simple, or proper fraction, is when the nu- merator is less than the denominator, as , , 3, 4, &c. 2. An Improper Fraction, is when the numerator ex *eeds the denominator, as , , ,”, &c. 3. A Compound Fraction, is the fraction of a fraction, oupled by the woºd of, thus, of ſº, of 3 of , &c. 4. A Mired Number, is composed of a whole number and a fraction, thus, Sł, 14", &c. 5. Any whole number may be expressed like a fraction by drawing a line under it, and putting 1 for denominator, thus, 8–1, and 12 thus, a, &c. 6. The common measure of two or more numbers, is that number which will divide each of them without a re- mainder; thus, 3 is the common measure of 12, 24, and 30; and the greatest number which will do this is called the greatest common measure. 7. A number, which can be measured by two or more numbers, is called their common multiple: and if it be the least number that can be so measured, it is called the leas common multiple: thus 24 is the common multiple 2, 3 ane 4; but their least common multiple is 12. To find the least common multiple of two or more num- bers. Rule.-1. Divide by any number that will divide two or more of the given numbers without a remainder, and set the quotients, toge- her with the undivided numbers, in a line beneath. 2. Divide the second lines as before, and so on till there are no two numbers that can be divided; then the continued product of the di- visors and quotients, will give the multiple required. | 44 nEDUCTION OF vºlcan Faactions.

REDUCTION OF WULGAR FRACTIONS, IS the bringing them out of one form into another, in or der to prepare them for the operation of Addition, Sul, traction, &c. CASE I. To abbreviate or reduce fractions to their lowest terms. Rule.-1. Find a common measure, by dividing the greater term by the less, and this divisor by the remainder, and so on, always di- viding the last divisor by the last remainder, till nothing remains: the last divisor is the common measure.” 2. Divide both of the terms of the fraction by the common mea- sure, and the quotients will make the fraction required. * To find the greatest common measure of more than two numbers, you must find the greatest common measure of two of them as per rule above; then, of that common measure and one of the other unmbers, and so on through all the numbers to the last; then will the greatest common mea sure lºst found be the answer REL-U-T-I-M OF --L-A-I- FR-CT-DN-5. 145 ºr, if you choose, you may take that easy method in Problem I. ºp-gº tºº.) ---------- 1.

RULE. “Compute the interest to the time of the first payment, if that be one year or more from the time the interest com- menced, add it to the principal, and deduct the payment from the sum total. If there be after payments made, compute the interest on the balance due to the next pay- ment, and then deduct the payment as above, and in like manner from one payment to another, till all the payments are absorbed; provided the time between one payment and another be one year or more. But if any payment be made before one year's interest hath accrued, then compute the interest on the principal sum due on the obligation for one -year, add it to the principal, and compute the interest or the sum paid, from the time it was paid, up to the end of the year: add it to the sum paid, and deduct that sum from the principal and interest added as above." “If any payments be made of a less sum than the interest arisen at the time of such payment, no interest is to becom puted but only on the principal sum for any period.” Kirby's Reports, page 49.

RULE. 1. Prepare the given number for extraction, by pointing off from the unit's place, as the required root directs. 2. Find the first figure of the root by trial, and subtract is power from the left hand period of the given number. 3. To the remainder bring down the first figure in the *ext period, and call it the dividend. 4. Involve the root to the next inferior power to that *hich is given, and multiply it by the number denoting the ºven power, for a divisor. 5. Find how many times the divisor may be had in the lividend, and the quotient will be another figure of the root. 6. Involve the whole root to the given power, and sub- tract it (always) from as many-periods of the given number as you have found figures in the root. 7. Bring down the first figure of the next period to the remainder for a new dividend, to which find a new divisor as before, and in like manner proceed till the whole be finished. Note—When the number to be subtracted is greater than those periods from which it is to be taken, the last ruotient figure must be taken less, &c. Ex-MPLEs. 1.

Nore.—The roots of most powers may be found by th: square and cube roots only; therefore, when any ever power is given, the easiest method will be (especially in t very high power) to extract the square root of it, which re duces it to half the given-power, then the square root o that power reduces it to half the same power; and so on till you come to a square or a cube. For example: suppose a 12th power be given; the squart root of that reduces it to a 6th power: and the square roo of a 6th power to a cube. Ex-MPLEs. 3.

A. C. A., N. Y., PRINTED ANL PUBLISHED by MACR, ANDRus, AND wooDRUFr. INTRODUCTION. Scholars, male and female, after they have acquired a sufficient knowledge of Arithmetie, especially in the fundamental rules of Addi- tion, Subtraction, Multiplication, and Division, should be instructed in the practice of Book Keeping. By this it is not meant to recom- mend that the son or daughter of every farmer, mechanic. or shop keeper, should enter deeply into the science as practised by the mer chant engaged in extensive business, for such study would engross a great portion of time which might be more usefully emplºyed in ae- quiring a proper knowledge of a trade, or other employment. Persons employed in the common business of life, who do not keep regular accounts, are subjected to many losses and inconveniences to avoid which, the following simple and correct plan is recommend ed for their adoption. Let a small book be made, or a few sheets of paper sewed toge- ther, and ruled after the examples given in this system. In the book, termed the Day Book, are duly to be entered, daily, all the transac- tions of the master or mistress of the family, which require a charge to be made, or a credit to be given to any person. N. article thus subject to be entered, should on any consideration be deferred till another day. Great attention should be given to write the transac- tion in a plain hand; the entry should mention all the particulars nº- cessary to make it fully º with the time when they took place; and if an article be delivered, the name of the person to whom delivered is to be mentioned. No scratching out may be suffered; be- cause it is sometimes done for dishonest purposes, and will weaken or destroy the authority of your accounts. But if, .. mistake, any transaction should be wrongly entered, the error must be rectified by a new entry; and the wrong one may be cancelled by writing the word Error in the margin. A book, thus fairly kept, will at all times show the exact ºute of a persons affairs, and have great weight, should there at any time be a necessity of producing it in a court of justice. - --ORM OF A L.A.W. ºor. 3. *JEREMlAH GOODALE, Albany, January 1, 1822.

The affectionate Instructor, who always feels a parental solicitude for the permanent welfare of his pupils, cannot in any way so much contribute to their success in life, with so little trouble, as to teach them to understand this abridged, complete and simple system of Book Keeping. It contains all the important principles of extended and expensive works on the science; all, in fact, that is necessary to be known by the Farmer, Mechanic, and Shopkeeper, relating to ac- counts; and yet with very little explanation and repeated copying and balancing the accounts, will be so fully understood and deeply impres- sed on the memory of scholars of common mind, as never to beforgot ton; while their knowledge of common arithmetick and practical pen manship will thereby be greatly improved.
