9/26/08- Commutative is that you can move around the numbers if there added by each other and the sum won't change 2+3=3+2. Associative is that if you have numbers inside of parenthesis and outside you can switch them in and out with addition or multiplication around the numbers and not change the sum (5+8)+3=(3+5)+8
