In class, your teacher says, "Okay, let's pretend we've got this number line." She pulls out her math notebook and begins working on problems involving numbers like 10009. You're shocked. You try counting them all the way down from 1 through 10009 in your head, but you can't seem to work it out! Eventually, you give up and go back for the next problem, which is 10009 + 2 = 10011.
