Lattice Multiplication

There is a reason they dont really teach this in schools as it is a bit clumsy, not always applicable and would require us to re-teach math basics in some areas.

Its a great tool in many situations though!

    This actually was how I first learned multiplication, but after learning the basics, everyone drops this because it's so much extra work. Unless it's a Lattice Multiplication test, you will not even finish, that's how long this takes.
