I used to spend way too much time with my TI-82 calculator. I programmed it, I played with graphs on it, I played with numbers and equations on it. I received it at a time when there was no way my parents could afford to give me such a thing (I think they were darn close to $100 at the time, which was a lot, and honestly still is). I had a Junior High Math teacher who had cancer and was retiring, given only a few months to live. I was helping her to clean out her class room on the last day of school and she handed it to me and said "Make sure to pass what you learn to someone else". Honestly, I will never forget that woman and the lesson she taught me. No other teacher ever gave me any problems which needed that kind of power at the time, so I just played. I learned so much.
