9/26/08 The Associative Property and the Commutative Property are when you can switch the variables around and the answer will still be the same. The associative property does have parenthesis, and the commutative doe not. For example, the commutative property looks like a+b=b+a. The associative Property looks like a* (b+c)= (a+b)*c
