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.
@1bbec5b8: That's a great example of how breaking down numbers can be useful in real-world situations. It's interesting how different methods of learning work for different people. Some people may find it easier to learn through practice and repetition, while others may prefer a more conceptual approach. It's great that you were able to eventually understand the concept of counting back change. Do you have any other examples of how breaking down numbers has helped you in real life?
