When there are ciphers at the right hand of the divisor, cut off the ciphers in the divisor, and the same number of figures from the right hard of the dividend; then divide the remaining ones as usual, and to the remainder (if any) annex those figures cut off from the dividend, and you will have the true remainder

Short Division is when the Divisor does not exceed 12.

RULE. Consider how many times the divisor is contained in the first figure or figures of the dividend, put the result under, and carry as many tens to the next figure as there are ones over.

Divide every figure in the same manner till the whole is finished.

Contractions in Division.

When the divisor is such a number, that any two figures in the Table, being multiplied together, will produce it, divide the given dividend by one of those figures; the quotient thence arising by the other; and the last quotient will be the answer.

NOTE. The total remainder is found by multiplying the last remainder by the first divisor, and adding in the first remainder.

2. To divide by 10, 100, 1000, &c.

RULE. Cut off as many figures from the right hand of the dividend as there are ciphers in the divisor, and these figures so cut off are the remainder; and the other figures of the dividend are the quotient.

SUPPLEMENT TO MULTIPLICATION.

To multiply by a mixt number; that is, a whole number joined with a fraction, as 81, 51, 63, &c.

RULE. Multiply by the whole number, and take 4, 1, 4, &c. of the multiplicand, and add it to the product.

COMPOUND ADDITION,

IS the adding of several numbers together, having different denominations, but of the same generic kind, as pounds, shillings and pence, &c. Tuns, hundreds, quarters, &c.

RULE.-1. Place the numbers so that those of the same denomination may stand directly under each other.

2. Add the first column or denomination together, as in whole numbers; 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 denomination, continuing the same to the last, which add, as in simple addition.*

1. STERLING MONEY,

Is the money of account in Great-Britain, and is reckoned 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 farthings; in the shillings, to 12 in the pence; and 1 in the pounds, to 20 in the shillings; therefore carrying as di rected, is the arranging the money, arising from each column, properly in the scale of denominations: and this reasoning will hold good in the addition of compound numbers of any denomination whatever.
