Back to the Hello from the On-line Math Tutor

Introduction
The topics of positive and negative numbers are important, and they are also similar, so are dealing with both of them here, in the same place. If these topic is new to you, we will likely be going fast, but you can go back and forth as often as you like. And we will be adding some problems for practice. If you want a review, we hope that this will be about right.

This is the newest section of the On-line Math Tutor, so we would especially like your comments.
