When I'm doing math in my head, I use a lot of tricks like the one here, breaking numbers into parts and dealing with the parts. However, this makes no sense at all when teaching math to grade schoolers. They need to be taught the basic methods of adding and subtracting, carrying, etc. Once they have those down pat, they can start using these tricks when they have to do mental arithmetic.

Anyone remember New Math from the sixties? I got A’s in math without knowing a single thing about what I was doing. A wrong answer didn’t matter...you just had to understand the process.

26+17=43

6+7= 13
Put the 3 in the ones column carry the 1.
2+1 = 3+1= 4 which ges in the 10’s column.
