Summarize the Associative Property and Commutative Property in complete sentences. Use examples.

Associative Property: The associative property is used in addition and multiplication problems. It states that no matter what numbers in the problem go in the parenthesis, the answer will be the same. A+(B+C) = (A+B)+C

Commutative Property: The commutative property is also used in addition and multiplication problems. It states that no matter where you move the numbers in the problem, the answer will be the same.
