You're a hero of mine so here is my story. Me in math class in 1996 - I had a TI-82 things are programmable so I have no formal education, my parents are illiterate, and taught myself to program, and I begged them to buy me one. I spent time learning how to code on it, writing from scratch, the game Spyhunter. I couldn't figure out how to draw with lines or pixels so I used ASCII or text. I presented this to my teach…

Seems like everyone has such a story about a teacher. „No you can’t read more advanced books because the current ones bore you“ etc etc What is the matter with these people.

Personally betting on the "crab bucket" mentality.

About 25 years ago my parents got me a Ti84 as a surprise for Christmas and they hid it in the attic so I couldn't find it in the meantime. A few months went by and a couple days before Christmas, when it was time to wrap the presents they couldn't find it anymore. My dad went out and got a Casio something as a late minute replacement, and that was the calculator I used in high school and I never knew about this stor…

Was this the first time you had realized that they did, in fact, love you the entire time?

If you count basic calculus as high school level, TI89's can do symbolic integration. They're usually banned on tests for that exact reason tho.

Can it do anything non-trivial? The algorithms for symbolic integration are extensive. My Casio could do numeric differentiation and integration. I used this to double check my answers in my exams. In fact, it still can as I still own and use it to this day.

It's quite good for what it is. Of course it will lose to Mathematica but I used mine heavily throughout physics to derive things symbolically.

My favorite cheap Casio is fx-115ES Plus 2nd Edition, $17 https://www.amazon.com/Casio-fx-115ESPLS2-Advanced-Scientifi... Includes GCD and LCM, some of the newer ones don't have them. If you want graphing, there is the newish fx-CG100 has a nice display, but they removed Casio basic, it now only has micro Python (way too awkward to type on a tiny keypad): https://www.amazon.com/Casio-ClassWiz%C2%AE-Calculator-Funct..…

I agree with you on the Casio fx-115ES Plus 2nd Edition. I picked one up two years ago for $11.41. It naturally writes out equations, has a backspace and is generally excellent. I still love my HP RPN calculators, but the fx-115ES works nicely for anyone who isn't using RPN or sympy.

Also a +1 for this calculator, it's really the best scientific calculator you can buy and a steal at the price it sells at.

Show me a highschool math problem you can't do on a $12 Casio scientific like the classic FX-300MS https://www.usaofficemachines.com/csofx300ms-fx-300ms-scient... There's even knockoffs of it for $1: https://www.aliexpress.us/item/3256809744184708.html I picked one up when the 99 cent store was shutting down. It works fine. Look what you can get for $20: https://www.casio.com/intl/scientific-calculators/product.FX...…

Most of those are counterfeit knockoffs and the buttons are unreliable. It's safer to buy an older, pre-VPAM variant of the 300 or 991 models.

You can turn off VPAM though, why would you not want it?

Yeah there's not really a purpose for advanced calculators anymore (apart from the niche market of people who just enjoy using them). Calculators are basically only a thing now to make it harder to cheat on exams. If you don't have that constraint, you might as well use Wolfram or Matlab or whatever.

Or, here's a wild idea - exam problems should be structured such that they do not require any advanced calculator. Math problems should not require any calculator. Physics problems should require a scientific calculator. Overcomplicating the arithmetic shouldn't be the point.

Calculators can do a lot of things; a lot of physics is greatly improved by access to a good calculator.

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.

Honest question: Why do we need physical graphing calculators anymore? Can't this just be a phone app? That screen resolution for one is horrible for 2026.

I am pretty sure I could use a TI-89 Titanium in the dark even now

In high school I had the TI-89 Titanium. Like everyone here, I got into programming it using some USB adapter I could attach to my iMac G5 and the TI Connect app[0]. One day, vexed by something, I vented my frustration by composing a profanity-laced rant into the Feedback window of the TI Connect app. (I don't recall the proximate cause, but I remember complaining that the product itself, which is still $110 today, i…

I just put up with TiLP which I somehow figured out how to build on macOS. I think I still have cruft from that attempt on my machine years later somewhere

for context tests like SAT, ACT, and some AP exams are using Desmos, yes however: - this means you have to fiddle with a popover window and can't always see the full problem (especially when the reference sheet is also online) - you have less muscle memory and often take longer - harder to multitask (you use paper anyways, and the paper to calculator friction is lower than the paper to trackpad friction - trackpads o…

Ideally the tests would not require external tools at all. There's nothing that needs to be tested in the context of a high school course that can't done with pencil and paper.

There are a lot of interesting problems that can be done with a calculator, though
