Monday- 9/29/08 (Summarize 2 Words) Commutative Property- Adding or X numbers in any order to produce the same answer. 3 + 7 = 7 + 3, 3 * 7 = 7 * 3**
 * Associative Property- Regrouping of numbers produces same answer in addition or multiplication problem, Numbers in parenthesis change but the answer doesn't. (6+4) + 5 = 6 + (4+5), (6 *4) * 5 = 6 * (4 * 5)
