Back

The identity property of addition states that any number plus zero equals the other number.

What is the commutative property of addition?

Back

The commutative property of addition states that changing the order of the addends does not change the sum. For example, 6 + 9 = 9 + 6.

What is the associative property of addition?

Back

The associative property of addition states that the way in which numbers are grouped does not change their sum. For example, (2 + 3) + 4 = 2 + (3 + 4).

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum.

Calculate: 4(2x + 3)

Back

8x + 12

Front

Calculate: 5(a + 6)

Back

5a + 30

Front

Calculate: 2(5 + 4)

Back

(2 x 5) + (2 x 4) = 10 + 8 = 18

What is the commutative property of multiplication?

Back

The commutative property of multiplication states that changing the order of the factors does not change the product. For example, 3 x 4 = 4 x 3.
