There are another good tricks, but this is really impressive.

I think you’re doing the same but with a graphic trick so you don’t have to remember the basic results, intead you count the intersections of the drawn lines.

Congratulations, you’ve discovered the polynomial equation.

Try 76 x 69. It’s not so convenient, or easy, and exposes that you’re not really using anything different than old-school multiplication.
