MULTIPLICATION OF SIMPLE NUMBERS.

$21. If Charles gives 2 cents apiece for two oranges: how much do they cost him?

Ans. 4 cents. If Charles gives 2 cents apiece for 3 oranges: how much do they cost him?

Ans. cents.

If he gives 2 cents apiece for 4 oranges: how much do they cost him? Ans. 8 cents. If he give 2 cents apiece for 5 oranges: how much do they cost him? Ans. 10 cents. The cost in each case, may be obtained by adding the price of the separate oranges; thus,

2+2=4 cents, the cost of 2 oranges, 2+2+2 6 cents, the cost of 3 oranges, 2+2+2+2=8 cents, the cost of 4 oranges, 2+2+2+2+2=10 cents, the cost of 5 oranges.

In the first case 2 is repeated two times, in the second case it is repeated three times, in the third, four times, and in the fourth it is repeated five times; and in a similar manner any number may be repeated as often as we please by adding it continually to itself.

MULTIPLICATION is a short method of repeating one number as many times as there are units in another.

The number to be repeated is called the multiplicand. The number denoting how many times the multiplicand is to be repeated, is called the multiplier.

The number arising from repeating the multiplicand as many times as there are units in the multiplier, is called the product.

The multiplicand and multiplier are called factors, or producers of the product.

The sign X, placed between two numbers, denotes that they are to be multiplied together. It is called, the sign of multiplication.

Q. What is multiplication? What is the number called which is to be repeated? What does the multiplier denote? What is the product? In the case of the two oranges, which is the multiplicand?
