What is a fact family?

Back

A fact family is a group of related addition and subtraction or multiplication and division equations that use the same numbers. For example, the numbers 2, 3, and 6 can form the fact family: 2 + 3 = 5, 3 + 2 = 5, 5 - 2 = 3, 5 - 3 = 2.

How do multiplication and division relate to each other?

Back

Multiplication and division are inverse operations. This means that if you multiply two numbers, you can find one of the original numbers by dividing the product by the other number.

Front

What is the product in multiplication?

Back

The product is the result of multiplying two or more numbers together. For example, in 4 x 5 = 20, the product is 20.

Front

What is the quotient in division?

Back

The quotient is the result of dividing one number by another. For example, in 20 ÷ 4 = 5, the quotient is 5.

How can you check your multiplication?

Back

You can check your multiplication by using division. For example, if you calculated 4 x 5 = 20, you can check by doing 20 ÷ 4 = 5.

What is repeated addition?

Back

Repeated addition is a way to represent multiplication. For example, 3 x 4 can be shown as 3 + 3 + 3 + 3.
