I still have (and use) my TI-85 from college - these things are tanks and the 85 had a ton of power and abilities (including fully able to run BASIC language programs, matrices, graphing and other engineering tools).

My HS age kids absolutely REFUSE to learn to use it though, despite how much it could make things easier.

Pardon the messy desk - cat prints all over everything thanks to my furry co-workers.

I think people at my school started with TI-83 in freshman year, switched to TI-86 for chemistry, and then to TI-89 for physics and calculus.

I came in with a TI-30Xa Solar and felt horribly outclassed. But, I found the fraction and scientific stuff a lot easier to use on the 30Xa.

I can’t trust the touchscreen calculator anymore because my fingers can’t feel the difference between the sticky 6 and the 9.

It was, and still is a significant learning tool for students above pre-algebra. It’s a robust design.

Surprising for me to learn that, but yes, it’s been in production for a couple decades.

Its sort of like how the HP-12c financial calculator was perfect for what people demanded, and the design hasn’t changed for a long time. It looks like a relic from 1981.

LtPowers@reddit

The reasoning was wrong but the message was correct. Being able to work out problems without a calculator is an essential skill.

[-]

skamunism@reddit

100%. It’s similar to why showing your work is important. You’re not just solving this specific math problem—you’re building a foundation for higher skills.

Small example, but when you’re in a meeting going over facts and figures, some people can extrapolate and reason with numbers to get to new questions, critiques, and conclusions, while others just sit there seeing “facts”. They may be able to work the basic equations, but they can’t build on it or be productive in a live conversation.

[-]

tagehring@reddit

Used to drive me crazy as a gifted kid, though. "What do you mean I have to show you how I got 'X=4'? X *is* just 4!"

[-]

LtPowers@reddit

Same. But I wish someone had explained to me why it was important -- both for the teacher and for the student -- to understand how the answer was achieved.

[-]

tagehring@reddit

Yeah, but at the time it struck me as as frustrating as having to explain *why* 2+2=4. At least until I got to AP Calc and had to start working through them.

[-]

LtPowers@reddit

Explaining why 2 + 2 = 4 is a very deep issue of mathematics theory, and not something a student would typically be asked. Did you perhaps mean something else?

[-]

skamunism@reddit

Kids love the “why” game—teachers and parents need to play it too.

[-]

rtxa@reddit

by the fact that overwhelming majority of people aren't, I'd say that's simply not true

very useful yes, essential no

[-]

LtPowers@reddit

Given the state of the world I think its absence is proof of essentiality, not of its inessentiality.

[-]

bluecyanic@reddit

And once you get into upper level maths the calculator helps less and that essential skill becomes even more important.

[-]

tagehring@reddit

I had an awesome math teacher in high school who was a computer programmer with DARPA back in her previous life. She was fine with us using programs on our TI calculators, but we had to show her the code and demonstrate that we wrote it ourselves by explaining what it did. Her theory was that if we could program it, we knew it well enough to have earned the labor-saving device, and if we didn't, that was on us if we screwed the code up.

Needless to say, this was before standardized testing ruined education.

[-]

Wyden_long@reddit

My senior year my math teach would say this. She was cool as shit though. We kept in touch and a few years ago she volunteered for me at an organization I worked at. Every time something needed to be calculated I would loudly say “LET ME TAKE MY CALCULATOR OUT OF MY POCKET.” while looking at her and she would pretend to get mad at me. After the third or fourth time someone asked why and she confessed to being that math teacher and from that point on it became a running joke in my office if she was there.

The 83 was the first graphing calculator to officially support assembly programming, but all of those other models could do it too except the 81, which didn’t have the port you could use to connect to it and load programs. TI just wasn’t going to help you do it.

Being a computer nerd I was also the only person in my friend group that had the graph link cable to connect TI calculators to a PC. I loaded my TI-86 up with games that way. I could easily share them with anyone that also had an 86 or with an 85 since the 86 was based on the 85. I also had a few friends with 83s that wanted games so I took one of their calculators home with me (on a day we didn’t have math homework, lol) and put a bunch of games on it from my PC and then they could share them with other 83s.

Back in HS, the TI-92 basically had legendary status among those in the know. I loved my TI-89 though, but only got that once I was in college. I was using the Tai-82 in HS.

As of 10ish years ago these were still required for my advanced college math classes. Justification is it was harder to cheat with since the instructor could watch us do the key-combo wipe.

Damn, I wish I still had mine. We had some good classes together. Lent it out in college and never saw it again 😭

I used the TI-85, 83, and 82. This post hit me in all the feels.

I still use the same TI-85 I had 30 years ago. I bought a second one off eBay for when I work from home. I mostly use it for unit conversions.

The teacher’s aide in my pre-cal “acquired” a ti-85 and sold it to me. I wished it would have been an 83.

Yes, I remember and no, I didn't secretly type in full math problems in notes and subtly use that on math tests.

I used mine for years as a technical support analyst calculating DTI and LTV beyind 2 decimal places to prove to people why the mortgage software that was rounding up, was in fact correct in that their client had exceeded underwriting guidelines.

All you rich kids with your TI-80-whatever calculators. I felt lucky to get one that had functions beyond just add/subtract/multiply/divide. Graphing was done on graph paper

I was in a technology museum in London and they had an original-flavour console to play pong. So I'm playing pong. Small child approaches and plays pong with me and is charmed with it because small children are easily amused sometimes. And I reflect that I remember playing it at their age.

Ow.

I also saw a payphone in a museum the other day as an exhibit. Almost keeled over and died right there.
