COMPOUND ADDITION. Definition.-Compound Addition is a rule by which several numbers of different denominations are collected together into one sum. D RULE. Place the numbers so that those of the same denominanation may stand directly under each other. Add the first row, or lowest denomination, together, as in simple addi tion, and divide the sum by as many of the same denomination as make one of the next greater: set down the remainder, and carry the quotient to the next superior denomination. Proceed thus through all the denominations to the highest, which add as in simple addition. The method of proof is the same as in simple addition. Note. Addition of money may either be performed by the precedng rule, or by the help of the pence table. |
