Question for the young'uns - calculators in school?

[Rape Fantasizer]

I don't remember when we were allowed to start using them. I think the basic stuff should be learned, but how many of you adults do math in your head? Most people use calculators anyhow. The TI-82, which was $90 and required when I was in high school, was the most difficult thing in the world to learn. We spent more time on that than on actual math. Little did the teacher know, we were all playing ping-pong and duck hunter on them.
