The TI-89 was ~$100 when I bought one 20 years ago. Looked it up on Amazon and they’re $100-$150 depending on the specific model. They haven’t kept up with inflation at all, which means they’ve been getting cheaper this whole time…

For 100$ you can buy new phone and install any math software you want

Grab the rom for whichever Texas Instruments calculator you like best and use one of the various TI8X emulators:

Just google for the rom file you want. I just tried the TI92+ found here:

Weird calculator, but one of the more common TI models should look just as nice

Thanks. I’ve been working with my state legislator to create new laws that give schools the legal ability to expel engineering students caught using Calculator rom’s. These roms have no business in education. I think with this information we can make great strides.

It isn’t too bad, but it is online-only subscribtion-based.

I mean, even just one that has the functions of a graphing calculator.

I use Calc84 on the Google Play store, free with minimal ads and a one-time fee to remove ads.
But it seems like others have found FOSS versions here.

For Android, CalcES. It’s modelled after the Casio scientific calculators, so if you’ve ever used those, the app will come naturally to you. Absolute must-have if you want to calculate anything complicated on your phone.

J (technically it’s a whole unique programming language with a learning curve that’s arguably more of a learning cliff, but it’s very heavily geared towards maths and also has some nice graphing modules)
