When the the US start doing it that ridiculous way? When I was in school we did it the Italy way. Is the the common core stuff.

If you have to expand and sum, then use (10+1)^2 instead of (8+3)^2.

Different procedure. Same result. This is the beauty of mathematics.

I am old skool math. My daughters came home with the " new math ". I have no clue how they do it. So I go to the skool and talk to the principal and their teachers. 2 + 2 = 4 what ever it was they taught my girls made it four times the work for the same correct results.
