  1. You'd've been pleased. I had a student in my study hall that I was tutoring in math. We were looking at the LCD of some fractions. We got to a number...don't remember the specifics...and they said, "Oh, we can't go any further because that's a prime number." Some math teacher somewhere taught him well. :)
