Counting back change is kinda like this. The charge is $7, you give me a $20. I say "7 and 3 is ten" and hand you 3x$1 bills. Then I hand you a $10 bill and say, "and ten is twenty." I didn't even have to do much math, I just counted up to what you handed me.

My dad made me do this whenever I had to make change in Monopoly. It was fucking murder. I think I was 30 before it clicked.
