Dear C.F.J., Seventh Grade Math Teacher,

Sure!, I do know of some interesting ways to help people understand the concepts and procedures behind the subtraction of negative numbers.

Before I throw any more never-before-seen math methods at our faithful visitors, I think the best thing I can do for you is to direct you to a couple of the ways we've presented before, each of which has resulted in an unusually hefty deluge of appreciative emails.

Our Q&A's are arranged chronologically and are accessible this way: 

First, go into our Q&A bank, which is one of the links along the left-hand side of the homepage of

Next, at the bottom of each screen you should see a horizontal list of numbered groups of past Questions-and-Answers.  Once you spot a horizontal list, use the 'next' and/or 'previous' icons, working your way back until you get to the April 13th, 2007 one called 'Subtracting Negative Numbers, Part II,' and the February 26th, 2007 one called 'Subtracting Negative Numbers.'

I think (and hope) that you will find them to be original and helpful.  Let us know, and if you wish, we'll see what else we can produce!

Good luck,
