That is a brilliant video!
Actually, I thought it was going to be about some convoluted lattice method. I was counting the time it took him to draw the "lattice" and insert the numbers.

In that time, I had done the problem in my head, using very simple (but requiring practice - imagine that!) technique. You can check out the basics of it at The MathMojo Chronicles.
