**Multiplication** is a way to add a number to itself a certain number of times.

In a multiplication sentence, the numbers that are multiplied are called

**factors**, and the answer is called the

**product**.

3 | × | 5 | = | 15 |

factor | × | factor | = | product |

Use repeated addition to find the product.

4 × 5 is the same as four 5's added together.

**Division** is a way to separate a number of objects into equal groups.

In a division sentence, the first number is called the

**dividend**, the second number is called the

**divisor**, and the answer is called the

**quotient**.

15 | ÷ | 5 | = | 3 |

dividend | ÷ | divisor | = | quotient |

Use repeated subtraction to find the quotient.

Subtract 8 from 16 until the difference is zero.

Eight subtracted from 16 two times equals zero.

So, the quotient is 2.
