“Wa wa wiwa!”

If Borat could see this he would certainly say Wa wa wiwa. Thanks to ivideo for bringing this to my attention. It is a simple and funny way to multiply, see for yourself:

I tested it with a bunch of numbers and it works fine, it is even sometimes faster than the usual way of doing it. I guess it would be a nice thing to try this in school when introducing multiplication in class.

    thank you ferramis,

    i used to like these kind of easy ways to calculate. just like the thing with 11 times xy where it’s x(x+y)y.. And in school i tried even finding ways to easily calculate 12 times xy but it wasn’t getting any easier..

    Anyway, i didn’t know this method.
