    I was programming a game and this one was driving me nuts. Since there are only two possible input configurations, one would think their order determines the direction of the output vector. Nice QUICK video though.
    I'm too lazy to program a test case because I'm dumb but it's either that or it's "arbitrary" in the sense that some property of the input vectors not obvious in person-terms causes it to go one way or the other.

      Its vectors mate. Mathematicians got in a room and said, 'ok, what is the newest set of rules that we want to make' and then they came up with this. On a real-world sense, it means nothing. But you can use the direction to determine other vectors, which, also mean nothing. Moral of the story is that you should give up extension 1 mathematics and just go work at chuck-e-cheese.
