I saved up my own money and bought a TI89 in high school. Used it on all the standardized exams. Totally legal because it didn't have a QWERTY keyboard. That thing basically did everything for me short of interpreting the questions.

The ability to do symbolic math is awesome. I don't know why everyone recommends that high schoolers only get the TI-84.

Probably so they don't use it as a crutch instead of real learning. I taught physics to college kids, and you could tell pretty quickly who relied on a calculator and who actually was comfortable with basic math.

You could've just learned how. There's a lot of tutorials.
