We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).

I used mine constantly in highschool (10 years ago).

I used mine in highschool (20 years ago) and still use one today.

I was in (Catholic) HS 30 years ago and we used our TI-82s extensively in AP Calc.

Probably have not touched mine since college.

Ti really needs to stop with the artificial product differentiation. There's no reason 15 years after the Nspire CX CAS came out that everyone of their calculators can't do CAS.

Advanced calculators are in an unusual space with external constraints on it. Some of the features or differentiation they add serves the constraint of "if you don't, we won't let students use it in the classroom". When a calculator is used in a classroom, there's a concern about people using the calculator to replace the skill that's being taught. So, for instance, there's space for a calculator with no CAS, for a c…

It is not really classroom. It is more so setting testing standard that matches the standardised testing that schooling aims for. This ofc then extends to testing in classroom tests as that is best way to prepare students.

Not that any of this matter anymore as it can be entirely replaced with LLMs in near future.

What calculators are you guys using that aren't in academia anymore and don't need the "exam approved" limitations? Or are we all just using software on our computers now. That would be sad. (I've had a Casio fx-991EX on my desk for a few years, that replaced a broken Casio fx-991ES. Though designed for academia, its operation is burned into my brain at this point.)

I used to keep my old TI-82 (or was it -84?) from high school and a simpler sturdy solar-powered calculator near my desk, but I realized I always just used either my computer (IRB in the terminal usually) or Apple's calculator app on my phone and never ever touched my physical calculators. So they've now been put in storage.

156MHz and 3,5MB user memory... Why do I feel like that is a joke these days.. I think some ESP32s are faster and have more memory, but not sure if they are fully comparable...

The comments on this are fascinating. Although, I was waiting for someone to chime in with "HP is better cuz RPN."

2 dinners out for a family of four would cover the cost of this calculator. If my kid's school required this for math, I wouldn't bat an eye at purchasing one.

I needed a Ti-83 for school in 1996-1998. If you couldn't afford one, the school would loan you one for the semester. Band instruments were the same way.
