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.

In 2008 I was in high school and wrote a TI-BASIC tutorial in German [0] on my blog that became by far the most popular thing I wrote - maybe on par with my post about how to fix a quest bug in Skyrim by teleporting Delphine.

I was a bit mad back then that people for some reason appreciated those posts more than many very deep teenager ramblings about politics/philosophy :D

I had programmed games, complex 3d visualisations (super slow but oh well), and was totally fascinated by what this device could do.
