Bill: When one of my students was calculating sight reductions much faster than the others, I checked which calculator he was using. It was the TI-30XA, and he was faster because it took him a lot fewer steps. He was also faster because he made fewer errors. Each step has the potential for making an error. At $13, all my other students bought one, and they're happily solving the equations now. It's a winner. It took me three sessions to get the class through that lesson. I could have done it in one.
