Math ... multiply & divide ... I assume you're using a base-10 number
system, so multiply or divide by 10 when your user's input indicates you
should do so.

I have one for you first. Are you using this list to do your homework?
I've noticed that over the past couple days you've been asking
not-necessarily PHP questions, but /basic/ programming questions.
For your repeating zeors question, you'll have to make use of some string
functions or a regexp function. Look for a pattern of more than 1 zero.
