Heh...reminds me in my Algebra II class, we were being taught polynomial expansion. I had a TI-89 which would do it automatically with a single function, but that wouldn't show the work, so I wouldn't get credit for it.

So I wrote a program that would show the work.

I asked my teacher if I could use that program on the test, and she said that if I knew the material so well that I could write a program that shows the work, then I'd probably ace the test without it anyways, so I could go ahead and use it on the condition that I did not share the program with any of my friends.

That condition was fine with me. I didn't have any friends. :-(
