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).

Agreed, it's insane to me that in an era of Google Colab (et al) schools still require students to shell out >$100 for one of these. I'm sure there is some backroom arrangement with schools of some kind.

There’s no back room arrangement, beyond perhaps some amount of marketing from TI to math teachers. But nobody is getting a kickback to recommend the TI-84. Also, since so many people had to buy these things then stuck it in a drawer after a couple years, there’s a healthy supply of used ones on eBay and marketplace.

My dad got a free palm pilot m125 or something and I used a ti/HP calculator emulator on it since my parents thought buying a $99+ calculator was too expensive. fun writing apps in basic for that thing and the games for it were the best mobile ones. I did envy people with Mario and drug wars on their calculators though.

I played the heck out of some space trading game based on drug wars I think. You “flew” around between planets buying and selling cargo. I would love to play something like that again on my phone.

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…

The fact that you made a game on a device that "wasn't for games" is even cooler.

You can write a game in almost every language. Check these ones written even on really low specs VM's:

My TI-85 story. While I was in prison, around 1996 or 1997, I found out a friend had a TI-85 calculator. I realized it was programmable, so I borrowed it over the weekend and wrote a program to track his stock portfolio. It was the first time I had programmed anything in 2 or 3 years. Then I learned that the US Bureau of Prisons had a rule against any calculator (or device) that was "programmable". So I programmed th…

Since we’re sharing stories…

In high school my stats teacher told us we had to get a proper calculator. She didn’t set any upper limit so i went down the calculators rabbit hole… and got an used ti-86 from 1999 off ebay for 35 euros (this was in 2007 or so).

I programmed software to solve exercises in ti-basic and spent every lesson doing essentially software testing: basically whenever a classmate was called to the blackboard to solve an exercise I’d input the exercise data and verified I got the right results.

I got 9.5 out of 10 to the immediate next test. The teacher took off half a point because i miscopied a number (0.3 rather than 0.03, i still remember that after almost 20 years). It would have otherwise been a perfect test.

Fun times.

I still have that calculator, i turn it on every now and then.

I remember naming that calculator “Annarita”, like a girl I used to like and that (of course, lol) barely knew I existed at all.

One time I wrote a game in English.

I learned programming on that calculator. I learned programming because of that calculator. I owe so much to that calculator.

Same. I distinctly remember my teachers having a debate around whether or not the functions I had programmed into my calculator were "cheating". On one hand, it was a tool and notes that I had access to my peers did not. On the other hand, I had created those tools myself, and if school was supposed to train me for the real world, wouldn't I be able to use the tools I created in the real world?

Wow, there were actually principles behind the rules and they bothered to reason about them. That's way different than my experience with school teachers.

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.

It's typical. They're supposed have authority and be better than you. That is the purpose of their position and their identity.

Don't be so quick to judge, because most people, including you would react the same way in similar contexts, for example if you were the top engineer at a company and someone started showing you up and being a hundred times better than you.

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...…

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.

The TI-89's have the same shell as the TI-83. I took the shell off the 83 and put it on the 89 as well as replacing some of the buttons.

I used this on tests that banned the TI-89.

Not really? I've worked with people who were super productive with high quality work, and my reaction was to... gravitate toward working more with them. Some people are status driven. Some are not. Some are apparently pathologically status driven such that they'll compete with a literal child.

In any case refusing to nurture such a child (even in effectively passive ways like letting them quietly do something more advanced with no specific instruction) and not being reprimanded for it would reveal that the actual purpose of their position is daycare worker, which should be a bigger strike to the ego.
