OMPOUND Multiplication teaches to multiply numbers or quantities consisting of divers denominations : also, to find the amount of any quantity at the given price of an integer. GENERAL RULE. Place the multiplier under the lowest denomination of the given quantity; then multiply it as in integers, and divide the product by as many of this denomination as will make one of the next greater; set down the remainder (if any) underneath, and add the quotient to the product of the next denomination, and so proceed." Note. In multiplying money, the learner may be taught to perform it without ufing divifion, by having the pence table perfectly committed to memory, and multiplying the fhilings as integers, carrying half the number of tens to the product of pounds, and prefixing the odd ten (if any) to the units place under fhillings. PROOF. Multiply double the compound quantity or price by half the multiplying integers; or half the former by double the latter; or invert the multipliers, when more than one. EXAMPLES. |
