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
Please tell me what calculator app is as nice as a physical calculator, I haven't found one yet
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.
Please be a joke. Please be a joke. Please be a joke.
I made my first fortune by stealing attention and selling it as a middle man without ever giving people a cut of the profits even though it was their time. I told them they would get new features like unskippable ads and progressive pricing for services they originally had but I now place behind a paywall.
Easy enough to do all this. Just put a fresh charming face on it like a Mr.Beast and give them a cut and they will rob every kid of their free time so I can sell it. But that industry is saturated I don't think most people have a minute in their day without being sold something now and it's hard to find a space to cram more ads into a persons day so I moved on.
I am now working to restrict peoples ability to find solutions to costly practices in order to keep the price of things like this inflated through legislation. Why should people be allowed to build their own solutions or fix products they're unknowingly licensing. Its not theirs.
Finally, an internet warrior actually helping the world!
Could you also address this single ply nonsense I've seen in stores? Half ply should be the maximum, the modern anus is far too coddled today and is turning us soft when we should all be hard
Poes law?
Thanks Melvin.

It isn't too bad, but it is online-only subscribtion-based.
The app can be bought with a one time purchase.
I mean, even just one that has the functions of a graphing calculator.

Quck search on fdroid
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)
