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.)

$160 at Amazon: https://www.amazon.com/Texas-Instruments-TI84-TI-Calculator/... Not as bad as I would've expected. Also, apparently it includes a very simple Python environment? https://education.ti.com/en/product-resources/eguides/eguide...

For a $10 BoM and maybe a year of R&D I would say that $160 is bad.

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.

It doesn't help students learn if the tool does everything for them. This isn't a tool for professionals.

Genuine question, who uses these in practice? In my experience, calculators beyond the basic were always banned in high school and college, cause everyone's so afraid people might store something into them, and afterwards it's just matlab and python. It's not like laptops aren't a thing that everyone has on hand.

You may have gone to a poor high school and college. I saw plenty of calculator use in high school and college a long time ago.

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 class that's trying to teach you to do algebra. That is in some ways easier than "don't use this function of the calculator".

I don't think it's been about costs or CPU for at least 20 years, but isn't it more that for kids to learn to do math, it's better not to have CAS always at hand? So that's why there are some in the lineup without it.

75” 4k OLED screens would have been unobtainable when I first used a TI.

10yrs ago they would have been 4 to 5 figures.

Now they are what? A couple hundred?

How in the world is a TI graphing calculator still $160? These 30yr old calculator chips apparently hold their value like gold…

Sure calculators were allowed in some cases, the "scientific" kind, not the graphing kind.

But yes I would agree. So much time spent making sure people don't learn to use the tools they'll always have on hand. Programming exams on paper and that kind of inane bullshit.
