What is the Identity Property of Addition?

Back

The Identity Property of Addition states that when you add zero to any number, the result is that number. For example, 5 + 0 = 5.

Front

What is the Additive Identity?

Back

The Additive Identity is the number zero, which, when added to any number, does not change the value of that number. For example, 0 + 2s = 2s.

Use the Distributive Property to rewrite: 4(h - 5g)

Back

4(h - 5g) = 4h - 20g.

Front

Calculate: -3(-7 + 2)

Back

-3(-7 + 2) = -3(-5) = 15.

Front

Use the Distributive Property to evaluate: (4 - 1)4

Back

(4 - 1)4 = 3 × 4 = 12.

Front

What is the Associative Property of Addition?

Back

The Associative Property of Addition states that the way in which numbers are grouped when adding does not change their sum. For example, (2 + 3) + 4 = 2 + (3 + 4).

Front

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, 3 + 5 = 5 + 3.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is the Multiplicative Identity?

Back

The Multiplicative Identity is the number one, which, when multiplied by any number, does not change the value of that number. For example, 1 × 7 = 7.

Front

What is the Associative Property of Multiplication?

Back

The Associative Property of Multiplication states that the way in which numbers are grouped when multiplying does not change their product. For example, (2 × 3) × 4 = 2 × (3 × 4).
