  1. LOVE this method. Thank you so much! It’s the first time I’ve heard of it, and it is so much easier than the methods I’d been taught in the past.

  2. I have always used this method since like the 3rd grade. once you get to a 3 digit by 2 digit numbers it takes an annoying amount of time

  3. this is awesome, i never even heard of this kind of multiplication, even after finishing uni

  4. Never heard of this method as well.
    I knew it was a good idea to review all the basics of math again.
