Think about it. Let's say you have some homework problems to do. The problem numbers assigned are 10-13. You then have to do 10, 11, 12, and 13.
That's 4 problems! Wake up guys everything you have been taught is a lie.

Yes 10-13 would be four problems however 13 minus ten is three because you don't subtract the ten If 13-10 was 4 that would be wrong it'd have to be 13-9 to be 4
