COMPOUND ADDITION.

Compound addition is the adding of sums or quantities which consist of several denominations.

RULE.

Place the sums or quantities so that the numbers of the same denomination may stand directly under each other, and form a separate column; then add up the several columns, successively, beginning with the one of the lowest denomination: if the amount of either of

the columns be not as much as 1 of the next higher denomination, set it down; but if it be, reduce it to that denomination, and add the number it contains of said denomination into the column of the same.

If a remainder occur on reducing the amount of any column, set it under that column. PROOF: as in Simple Addition.
