An analogy for those who claim to have no math problems, but still have:

Imagine shooting from a rifle to a train fast passing by. My rifle is 10x slower than yours. So, while a train passes, on average, you will get 10x more hits on it than me. However, if my rifle can shoot only once a minute and there is fast (or short) train, you can hit it .. once or twice, while I may happen than I completely miss it.

Understand now?
