The commutative property means you can move around the numbers in an addition and multiplication equation, and still get the same answer. Associative property means you can move whole groups of numbers and still get the same answer. But remember, this does not work for subtraction or division. The multiplicative identity is if you can multiply the number by 1, and it stays the same. The additive identity is if you can add 0 to a number, and it also stays the same. We know that's a lot, so take a small break while you recover from all this info.
