I'll get you started.
You'll need a new hundred.
You won't need a new ten or thousand.

sorry for the delay.. I don't understand. I do understand that a new 1000 is not needed because once added, it's still 1000 but as as far as the rest, I don't understand. Trying to help my daughter with her math homeworl!
