Math is hard. That's why America has fallen so far behind in mathematics compared to other nations around the world. It's full of complicated algorithms and greek symbols, and I want no part of it.
But once you see how the Japanese approach multiplication, you'll be blown away by how simple math suddenly seems. They really have it down. It's a shame that we weren't taught like this.
That was incredible. It required very little math at all -- just a couple of lines. That trumps the way I learned how to do it!
