9-29-08 The Associative Property is a property that involves either addition, or multiplication. It involves switching the parentheses, or order that you solve the problem in. The answer stays the same. e.g. (22*3)*9=(3*9)22 The Commutative Property is a property that involves either addition or multiplication. It involves switching around the order i which you solve the problem, by moving around numbers, however the answer will stay the same. e.g. 5+22+38=38+22+5
