What is the Associative Property of Addition?

Back

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

Front

What is the Commutative Property of Addition?

Back

The Commutative Property states that the order in which two numbers are added does not change their sum. For example, a + b = b + a.

Front

What is the Identity Property of Addition?

Back

The Identity Property states that adding zero to any number does not change the number. For example, a + 0 = a.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, meaning you can distribute a number across a sum.
