COMPOUND ADDITION, IS the adding of several numbers together, having dif ferent denominations, but of the same generic kind, pounds, shillings and pence, &c. Tuns, hundreds, quar

ters, &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 directed, 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.
