The hints need just a little work, but pretty good.

Notice there are links to the Commutative Law of Addition and Associative Law of Addition (and distribution), but not to the laws for multiplication.

Now for the idea... might be useful to have the full law stated. I've seen students who could accurately identify one, but not the other. So I'd see Commutative Law of Addition where it should have been Commutative Law of Multiplication.
