I’m not sure if this is actually how the Japanese multiply, as the video claims.  I am sure, however, that it is now the way that I multiply.  All this time I’ve been doing math when I could’ve just been counting!

As soon as I watched this video I whipped out a pen and a pad of paper and said to my wife, “Want to see something cool???”  She displayed a surprising lack of enthusiasm.
