Cool video. But you should mention that you can MAKE a subtraction commutative by turning it into an addition problem. That is: 7- 5 is not commutative but 7 + -5 is commutative, and it means the same thing. As long as I take the negative sign along with me, I can say -5 + 7 and I will get the same answer: 2.
