Pretty stupid, quite ineffective with digits above 4, and it's exactly the same process as just multiplying in your head except you have to draw a billion lines first. I could see this as useful with many-digit numbers that have no digits above 4, I guess. Other than that, its only use is to amaze people who don't understand math.

Takes a bit of logical reasoning to figure out how this works, but it's pretty cool. Have to realize he's doing this slowly to demonstrate. He could probably do the same operations in 1/4 the time.
