COMPOUND MULTIPLICATION.

Compound Multiplication is the multiplying of any sum or quantity which consists of divers denominations. When the multiplier does not exceed 12, work by

RULE 1.

Multiply the several denominations of the given sum or quantity, one after another, beginning with the lowest: if the product of either of them be not equal to one or more of the next higher denomination, set it down; but if it be, reduce it to that denomination, and add the number it contains thereof to the product of the same; and so proceed. If, on reducing the product of any denomination, there be a remainder, it must be placed under that denomination. PROOF.

Double the multiplicand, and multiply by half the multiplier.

When the multiplier exceeds 12, and is the product of two factors in the multiplication table, work by

RULE 2.

Multiply the given sum by one of said factors, and then multiply the product by the other factor.

PROOF: Change the factors..

When the multiplier is not the exact product of any two factors in the multiplication table, work by

RULE 3.

Use those two factors whose product is the least short of the multiplier; then multiply the given sum by the number which supplies the deficiency, and add its product to the sum produced by the two factors.
