So in order for a 7 year old to learn simple subtraction. They have to learn how to divide the first number by 2 then start solving the problem? Who came up with this mess? I don’t even know how to help him because it seems so unnecessarily complicated to solve it the way the book shows.

What was wrong with the old school way?


What if it’s 21-9?

10.5 and 10.5?
