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, 6 * 7 = 7 * 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).

Front

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.

Front

What is the Additive Inverse Property?

Back

The Additive Inverse Property states that for every number, there is another number that, when added together, equals zero. For example, 5 + (-5) = 0.

Front

What is the difference between a base and an exponent?

Back

In an expression like 2^3, 2 is the base (the number being multiplied), and 3 is the exponent (the number of times the base is multiplied by itself).
