What is the definition of the Commutative Property?

Back

The Commutative Property states that changing the order of the numbers in an operation does not change the result. For example, a x b = b x a.

Front

What is the definition of the Associative Property?

Back

The Associative Property states that the way in which numbers are grouped in an operation does not change the result. For example, (a + b) + c = a + (b + c).

Front

What is the definition of the Distributive Property?

Back

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