Here's how you could have answered your teacher. "Let these fingers represent positive numbers.", holding up three fingers. "Now, let these fingers represent negative numbers.", holding two fingers pointed down. (A side note, only a physicist would think of this, plus and minus spin and all of that. Don't you know?) "Now, if I ADD these two numbers, I get.....", holding up just one middle finger. Can you say expelled, I knew you could. Oh well, life is full of missed chances. R. Piner
