Multiplication and Division

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 x 4 means adding 3 four times: 3 + 3 + 3 + 3 = 12.

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 ÷ 3 means splitting 12 into 3 equal parts, which equals 4.

What is a fact family?

Back

A fact family is a group of related addition and subtraction or multiplication and division facts that use the same numbers. For example, the numbers 3, 5, and 15 can form the fact family: 3 x 5 = 15, 5 x 3 = 15, 15 ÷ 5 = 3, and 15 ÷ 3 = 5.

What is the product of 7 x 7?

Back

The product of 7 x 7 is 49.

Front

What is the quotient of 81 ÷ 9?

Back

The quotient of 81 ÷ 9 is 9.

Front

If 8 x 8 = 64, what is 64 ÷ 8?

Back

64 ÷ 8 = 8.

Front

What is the missing number in the fact family: 10 x 3 = 30, 3 x ____ = 30?

Back

The missing number is 10.

Front

What is the relationship between multiplication and division?

Back

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

Front

What does it mean to multiply by zero?

Back

Multiplying any number by zero always results in zero. For example, 5 x 0 = 0.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in a multiplication problem does not change the product. For example, 4 x 5 = 20 and 5 x 4 = 20.
