They had TI-85's in late '90s? I remember there only being TI-83s.

They did! The TI-89 is how I aced the AP Math exam. The TI-92 had recently come out, and it had a QWERTY keyboard and could solve symbolic calculus problems like "find the derivative of 2x^3". This was a problem for the AP exam, since you could just type in the problem and get the answer. They fixed this by banning calculators with QWERTY keyboards. That's just about exactly when the TI-89 came out, which also did sy…

Got the 89 first year it came out, loaded a periodic table on it and used it on my high school chemistry exam. Teachers had no clue back then

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...…

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.

My high school required one for a math curriculum that was specifically designed with the idea that students would not need advanced math classes. It kids up for failure if they were hoping to move toward higher level math in college, as the fundamentals were never adequately taught. But at least they sold thousands of calculators to kids who would never use them again. They actually started us on them in 7th or 8th…

$100 for something you'll use all through middle and high school and into college isn't a bad deal.

I would have preferred a proper math education. I would have paid more for that.

I actually need a TI-82 in 7/8th grade, a TI-83 in high school, then college wanted a TI-89. I was having to upgrade every few years.

Are we expected to know latin, or is this supposed to be a little homework assignment for us? Ridiculous.

Rather obviously these days one can copy/paste the Latin into google translate in mere seconds for relief ...

Google? Eeewwww!

the best calculator is of course a RPN calculator, preferably a HP 48GX, but HP Prime also suffices. Swissmicros DM42N is a good second :-)

How long were you locked up in the clink for? Did you get any access to computers there? How did your time there affect you or change how you think? Thanks for sharing

I still have my TI-83 plus. It's been with me for 25 years now! I've always kept it on my desk, despite the fact that I engraved 'KoЯn' on cover when I was 13 or 14.

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…

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.

Space trader?

I played it recently on iOS via the palm web emulator
