A man travelled 26 days, and each day, he travelled 37 miles ; what distance did he travel in the whole time ? Ans. 962 miles, SIMPLE DIVISION. DEFINITION --Simple Division teaches to find how many times a smaller number is contained in a larger. The number given to be divided, is called the dividend. That number which expresses the number of times, that the divisor is contained in the dividend, is called the quotient, or answer. If any thing is left after dividing, it is called the rempainder. LONG DIVISION. Long division is when the Divisor is more than twelve. CASE I. RULE..Write down the dividend, on the right and left draw a curved line ; on the left hand of the dividend write down the divisor; seek how many times the divisor can be had in a competent number of the first figures of the dividend, and place the figure expressing the number of times, at the right of the dividend ; multiply the divisor by the same figure, and place the product under the first figures of the dividend, and subtract; to the remainder bring down the next figure of the dividend, and divide as before ; and thus proceed until all the figures of the dividend are brought down; if at any time when you have brought down a figure the sum is still less than the divisor, a cypher must be placed in the quotient, and another figure must be brought down; the remainder must always be less than the divisor. Proof.--Multiply the quotient and divisor together, to the product add the remainder (if there is any) and the sum will be like the dividend, if the work is right. Examples Dividend.

When there are cyphers at the right of the divisor, RULE.--Cut off the cyphers, and also cut off as many figures, or cyphers from the right of the dividend; divide the remaining part of the dividend as before, and to the right of the remainder, place the figures which were cut off from the dividend. as on Eramples. 432 1322 26321 Rem. 63-82.13 60_232 1.

NOTE:--To divide by 10, 100, or 1000, &c. is only to cut of as many figures, or cyphers from the right of the dividend as are equal to the number of cyphers on the right of the divisor.

RULE.--Seek how many times the divisor is con.. tained in a competent number of the figures on the left hand of the dividend, and set the figure express... ing that number underneath, and all that is over call so many tens, annex the next figure of the div-. idend to the tens, divide as at first, and thus proceed through the whole, and the quotient will stand. under the dividend.
