He has founded his work on the belief at labor and labor only, can insure success in any pursuit; and | that labor should always be bestowed upon those objects which pro- uce the greatest useful result. * | In the selection and arrangement of matter, therefore, those rules || t are of the most general use, have been presented first, and their || | exercises made extensive, that the pupil many early become familiar with their principles, and expert in their application. $ º | The explanations accompanying the rules, are designed to facili- || |tate the progress of private students, and to diminish the labor of | eachers, especially in large schools, where they are unable to give | o each pupil the necessary explanations. s || he MENsun ATIon of Carpenters’, Masons', Plasterers’ and || ºrs’ work, &c., will be found an acceptable part of Arithmetic, I every man of business, and a practical knowledge of it will con- tribute much to the security and satisfaction of both workmen and || mployers, in estimating amounts of work. This has been intro- ced in consequence of numerous applications to the author to || easure various kinds of work, and for instruction in particular || es of Mensuration. -* - - | The system of Book Keeping, is thought to be sufficient for all || e purposes of farmers, mechanics and retailers, in that necessary || anch of a business education. . . How far the author has succeeded in his attempts to compile a || ful work, particularly adapted to the circumstances of the Western || ople, remains for them to judge, and for experience to determine.] The favorable reception of this treatise and the increasing demand | , have induced the publishers to revise, enla vuerwise || rove the work. Such alterations and amendments have been| ide as the experience of the author and of other intelligent and | x will be found more useful, and consequently more umerous testimonials to the merits of the work, have been re- ed; but its general adoption without any efforts to force its || . luction, and its intrinsic worth, are our main reliance; we have ARITHMETIC. &º ARITHMETIC is that part of MATHEMATICs which || treats of numbers. It is both a science and an art;- | the science explains the nature of numbers, and the principles upon which the rules are founded, while the art relates merely to the application of the various || rules. - || All the operations of arithmetic are conducted by | means of FIVE fundamental rules, viz., Numeration, | which includes Notation,) Addition, Subtraction, || wltiplication, and Division. § NUMERATION AND NOTATION. Numeration is the art of representing figures or num- || | bers by words; Notation is the art of representing num- || | bers by characters called figures. || | All numbers are represented by the following charac- | ters, which are called figures or digits. | | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. | nought, one, two, three, four, five, six, seven, eight, nine. | The one is often called a unit, it signifies a whole | thing of a kind; two signifies two units or ones; three || | signifies three units or ones, &c. - || | The value which the figures have when standing || | alone is called their simple value; but in order to denote | | numbers higher than 9, it is necessary to give them ano- || || ther value called a local value, which depends entirely || | on the order or place in which they stand. Thus, when || | we wish to write the number ten in figures, we do it by combining the characters already known, placing a || || 1 on the left hand of the 0, thus, 10, which is read ten. | This 10 expresses ten of the units denoted by 1, but || | as it is only a single ten it is called a unit, and the [ 1 being written in the second order or second place || | from the right hand to express it, it is called a unit of || º || the second order, the first place being called the place || º F- 5 ºśº - ;:...º.º.º.º. NUMERATIon AND NoTATIon. of units, and the second, the place of tens ; ten units || the first order making one unit of the second order. || When units simply are named, units of the first order |are always meant, when units of any other order are || | intended, the name of the order is always added. §§ºš | Two tens or twenty, are written 20. |*Three tens or thirty, “ . . 30. | Four tens or forty, “ “ 40. | Five tens or fifty, 4 & & 4 50. | Six tens or sixty, “ “ 60. | Eight tens or eighty, 4 & & 4 80. | Nine tens or ninety, “ 4 & 90. | Ten tens or one hundred, “ { % 100. || | The numbers between 10 and 20, between 20 and || |30, between 30 and 40, &c. may easily be expressed || |by considering the tens and units of which they are || |composed. Thus, eleven being composed of one ten || and one unit, is expressed thus, 11, twenty-three being || || composed of two tens, and three units, is expressed || |thus, 23. &c. w - | Sixteen being 1 ten and 6 units, is written thus, 16. | Thirty-nine being 3 tens and 9 units, is written 39. I Sixty-four being 6 tens and 4 units, is written 64. || Ninety-five being 9 tens and 5 units, is written 95. || | | Ten tens or one hundred forms a unit of the third || order; it is expressed by placing a 1 in the third place, | ind filling the first and second places with cyphers, i. us, 100. Two hundred is expressed thus, 200. | Three hundred thus, 300, &c. * {} With the orders of units, tens, and hundreds, all the | & º, mbers between one and one thousand may be readily || d its, that is, 4 units of the third order, 2 units of the . . . ; ence the number is written thus, 4 27 the number three huudred and five, the pressed. For example, in the number four hundred | twenty-seven, there are 4 hundreds, 2 tens, and 7 || & cº º 3 O 5 Ten units of the order of hundreds, that is ten hun- dreds form a unit of the fourth order, called thousands, | written thus, 1000. . In the same manner ten units of the fourth order form a unit of the fifth order, called tens of thousands. The following may be regarded as the principles of | Notation and Numeration. 1st. Ten units of the first or lowest order, make one | unit of the second order; ten units of the second order, make one unit of the third order, and universally ten | units of any order make a unit of the newt higher || | order. || | 2d. All numbers are expressed by the nine digits, | and the cypher, and this is effected by giving to the | same figure different values according to the place it i occupies. Thus, 4 in the first place is 4 units, in the | second place 4 tens or forty, and so on. This tenfold || | increase of value by changing the place of the same || | figure is usually expressed by saying that figures in- || | crease from right to left in a tenfold proportion. The | names of the orders are to be learned from the : NUMERATION TABLE, # : . | if : f | | The orders are likewise divided into periods of fix | | places each, according to the following table. º º NUMERATION AND Notation. 7. none of the second, and five of the first order, hence the || number is written thus, ă ă # * } ... of Mj llions. 3. * # * f f t ºr: i # # c ...~ ſ | i ſ # tº d º 5- É. . The periods succeeding those in the table, are Tril- | || lions, Quadrillions, Quintillions, Seatillions, Septil- || T F- P T || might be formed for the sueceeding higher periods. | From the preceding remarks the pupil will readily || understand the reason of the following rule for numer- || |ating or expressing figures by words. ; Rule.—Commence at the right hand, and separate || | e given number into periods, then beginning at the left || | land, read the figures of each period as if they stood || º | || alone, and then add the name of the period. || | Thus, the number 8304000508245, when divided || | into periods, becomes 8,304000,508245, and is read, | Eight billion, three hundred and four thousand mil- || | || lion, five hundred and eight thousand two hundred | || and forty-five. The name unit of the right hand pe- || | riod is commonly omitted in reading. % º Exercises IN NUMERATION. || | Ex. 1. 35 | 10. 37.00054 | 19. 20031025 || 2. 204 || 11. 6130425 | 20. 68723145 || 3. 513 | 12. 2701030 21. 901023406 || 4. 2000 N. ~ 3.3% 5, 3054 14. 6803217 |23. 310275603 || 6, 7428 i 15, 2003005 || 24. 600000501 || 7 10345 | 16. 70032004 || 25. 300040023.0024 || 8.400.24 || 17. 62003005 |26. 80000102051003 || 9. 61304 | 18. 91010010 | 27. 50000021375604 || lions, Oetillions, and Nonnillions, and analogical names || | 13. 3705423 22. 820302008 || Tº :RATION AND NoTATION. | 9 | i | From the preceding tables and remarks, the pupil will || likewise readily understand the reason of the following | rule for notation, or expressing numbers by figures. RULE.—Make a sufficient number of cyphers or dots, and divide them into periods, then underneath these || dots write each figure in its proper order and fill the vacant orders with cyphers. 3. NoTE.—The object of the dots or cyphers, being to guide the learner at first, after a little practice he may dispense with them. Ex. 1. Write down in figures the number twenty millions three hundred and four thousand and forty. Here millions being the highest period named, we | write cyphers to correspond with that, and the period | of units, and then underneath these place the significant || | figures in their proper order, and afterwards fill the vacant orders with cyphers. 0 0 0 0 0 0, 0 0 0 0 0 0 2 0 3 0 4 0 4 0 º The pupil must recollect that cyphers being of no | use except to fill vacant orders, are never to be placed || | to the left of whole numbers. - EXERCISES IN NOTATION.

COMPOUND SUBTRACTION. | CoMpound SUBTRACTION is the art of finding the dif-|| |ſerence between two numbers consisting of several de- |nominations. | RULE. | Place the numbers, as in compound, addition with the |less under the greater: then begin at the right hand || |denomination and subtract the lower number from the || |upper, and set down the remainder. | If the upper number of any denomination be less than || |the lower one, add to the upper one as many as it takes || |of that to make one of the next; subtract the lower num-l |ber from the amount and set down the remainder as || |before. § 3. 3 § | Proof–As in simple subtraction.

But the cube root is the length of one of the sides of the cube, whose length, breadth and thickness are l equal: then the cube whose || root is 20, contains 20X20 || - X20=8000. ~ “Subtract the cube thus || found (8) from sand period, and to the remainder bring || down the next period,” or, subtract the 8000 from the whole given number (15625) and 7.625 will remain. Thus || 8000 feet are disposed of in the cube, Fig. 1. 20ft long, | 80 ft wide, and 20 ft. nigh. . The cube is to be enlarged by the addition of 7.625 feet i which remain. In doing | || this, the figure must be enlarged on three sides, to make it longer, |and wider, and higher, to maintain the complete cubic form. | The next step is, to find a divisor; and this must be the number of |square feet contained in the three sides to which the addition must be t! |imade. . . - . 2 º' }: | Hence we “multiply the square of the quotient figure by 300.” | |That is, 2X2X300=1200: or 20X20 × 3–1200 feet, which is teſ | superficial content of the three sides, A, B, and C. . ſubrº ROOT. This “divisor (1200) contained in the dividual” || (7.625) 5 times: then 5 is the second quotient figure; that || is, the addition to each of the three sides is 5 feet thick; if| 1200 feet cover the three sides one foot thick, 5 feet || thick will require 5 times as | many; that is 1200×5–|| 6000. | But when the additions || are made to the three squares || there will be a deficiency along the whole length of || the sides of the squares be-|| tween the additions, which || must be supplied before the cube will be complete. These || deficiencies will be three, as || I may be seen at NNN in Fig. 2; therefore it is that || we “multiply the square of the last figure by the prece- ding figure, and by 30," | (that is, 5×5×2X30,) or || 5X5×20×3=1500which || is the quantity required to || supply the three deficiencies. || Figure 3, represents the solid with these deficiencies || supplied, and discovers an- other deficiency, where they | approach each other at ooo.

ARITHMETICAL PROGRESSION. | Any series of numbers increasing by the constant addi-|| |tion, or decreasing by the constant subtraction of the same || |number is called an Arithmetical progression. When || |the series is formed by the constant addition of the same| |number, it is called an ascending series, but when the |series is formed by the constant subtraction of the same|| number, it is called a descending series, thus: "| | 1, 3, 5, 7, 9, 11, &c. is an ascending series. || ||20, 17, 14, 11, 8, 5, &c. is a descending series. || | The number which is added or subtracted continually || |is called the common difference; in the ascending series|| |above, this is 2, and in the descending series it is 3. |The numbers which form the series are called the terms || |of the series or progression.

THIs book is used to collect the scattered accounts of the Day Book, and to arrange all that relates to each individual, into one separate statement. The business of transferring the accounts from the Day Book to the Leger, is called posting. The Leger is ruled with a double line in the middle of the page, to sepa- rate the debits from the credits. Each side has two columns for dollars and cents, one for the page of the Day Book, from which the particular item is brought, and a column for the date. . When an account is posted, the page of the Leger on which this account is kept, is written in the column for that purpose in the Day Book, and also the page of the Day Book from which the account was posted, is written in the 2d column of the Leger. In posting, begin with the first account in the Day Book, which you will perceive is the name of David Judkins. Enter his name in the first page of the Leger, in a large, fair hand, with Dr. on the left and Cr. on the right.— As there are several articles charged to D. Judkins on the 4th of January, instead of specifying each article in the Leger, we merely say, For Sundries, and enter the amount in the proper columns—see Leger, page 1. The Leger has an index or alphabet, in which the names of persons are arranged under their initial letters, with the page in the Leger where the account may be found. ALPHABET TO THE LEGER.
