Math CentralQuandaries & Queries


Question from Janelle, a student:

I had a friend try and play a game on me, regarding phone numbers, so I only know the area code , and the last four digits of the phone number. Which means, there are 3 digits that I need to figure out all the possibilities to.

Hi Janelle,

Think about them in order starting with 000, 001, 002, ... and ending at 999.
