WHEN any sum or quantity consists of several denominations it is called a compound quantity, as £10 2 s. 3 d.; and the adding of such sums or quantities together is therefore called compound addition. That number or parts of any denomination which is equal to 1 of the next higher denomination, is called a unit measure; thus, 12 d.=1 shilling, the unit measure of pence, therefore, is 12; so 20 shillings £1, and the unit measure of shillings is 20, and in like manner for other denominations. RULE. Arrange the sums or quantities so that the same names or denominations may stand directly under each other; then begin at the lowest denomination, and add up the columns, as in simple addition; if the amount of either column be less than the corresponding unit measure, set it down; but if it be more, divide it by the unit measure, carry the quotient to the next column, and set down the remainder. Proof as in simple addition. ENGLISH MONEY. EXAMPLES. £ S. d. 10 2 3 45 10 2 36 9 1 20 7 0 112 8 6 OPERATION. We begin with the pence column, and say 1 added to 2 make 3, and 3 added to 3 make 6, which we set down underneath; then, beginning at the next column, we say, 7 added to 9 make 16, and 10 make 26 and 2 make 28; and because the unit measure of shillings is 20, we divide 28 by 20, whence we have 1 for the quotient and 8 for remainder; hence we put down the 8 and carry the 1 to the next column; this last column we add up, and put down the whole sum.
