I am almost afraid to ask this. First, I probably won't understand the explanation anyway. Second, the answer I have just brings a lot of quibbling thoughts to mind. Nevertheless, I'll try and hope there is a math genius here who can explain in very simple terms why:
-3 x -3 = 9. Why doesn't -3 x -3 = -9? A friend says she was taught that two negatives cancel each other out. In that case, why wouldn't two positives cancel each other out?
Can someone show me why -3 x -3 = 9? I shall be most grateful.
Thanks.
