I received the TI-83+ manual on the first day of high school and read it back-to-back that same day.

Subsequent math classes, I started by writing a BASIC problem to solve the type of math problem we were given.

I can't decide if I got really good at solving those math problems by solving them generally once, or really bad at solving those math problems for never having solved them more than once or twice by hand while writing the program.

Those programs were very inefficient, and you could code the TI-83+ in assembly, but it required uploading the code via cable. I recall being able to play small internet-downloadable network games with two TI-83+ connected. I never got around to writing any games myself.
