SIMPLE MULTIPLICATION

Is a compendious way of adding numbers of the same

name.

The number to be multiplied is called the multiplicand. The number which multiplies is called the multiplier. The number arising from the operation is called the product.

Rule. Place the multiplier under the multiplicand, and multiply the latter successively by the significant figures of the former; if the multiplier consists of more figures than one, place the right hand figure of each product under the figure from which it arises; then add the several products, and their sum is the product of both factors, and the answer required.
