I wondered why it is that when you multiply a negative with a negative, you get a positive?(adsbygoogle = window.adsbygoogle || []).push({});

in example; why is it that -3 x -3 = 9?

when you do -3 x 3, the answer is intuitively -9, because you just go three times as negative. But when I multiply two minus signs, I don't have this intuition it should be positive, except for the fact that it's the only thing left.
