I paid about $100 on it when I was in college .... 10 years ago. If you factor in inflation, the price here $76 is actually pretty good. I'd get one if I need it

I bought TI-89 back 1991 when I took Linear Equations. My professor made me to buy it. It was requirement to pass his class. //@Anonymous: I paid about $100 on it when I was in college .... 10 years ago. If you factor in inflation, the price here $76 is actually pretty good.

Tell your professor that linear equation existed before graphing calculators and show him how to do it by hand. j/k, mostly, of course, but seriously. //@Anonymous: I bought TI-89 back 1991 when I took Linear Equations.

I still have my casio scientific calculator from 30+ years ago and it still works. It got me through 2 engineering degrees. They might have been the first to have calculators with continuous calculation (exe instead of equal sign). I bought one of those TI financial calculators just for my professional engineering exam and it broke right after. I think there is a conspiracy to promote TI products in the US in schools. Just look at a syllabus and see if there is mention of casio. Casio was better than TI in my days and I still think it is.

I had a Casio graphing calc in hs. Piece of junk used coin cell batteries that needed replacing every 3 weeks. When I got to university, I skipped the "kids" calculators and bought an HP RPN

I am using a Ti-84 Plus CE from several years ago. Previously, I used my Casio to get my Ph.D. degrees. But, I will never go back to Casio again. TI is fantastic.
BTW: I teach college-level engineering mechanics. TI-84 plus is good enough for most engineering courses, but I will recommend a newer/higher version.

If your engineering students are going to take PE exam(s), please read below: "To protect the integrity of its exams, NCEES limits the types of calculators examinees may bring to exam sites. The list of approved calculators is reviewed annually.

The following calculator models are the only ones acceptable for use during the 2020 exams:

Casio: All fx-115 and fx-991 models (Any Casio calculator must have “fx-115” or “fx-991” in its model name.)Hewlett Packard: The HP 33s and HP 35s models, but no othersTexas Instruments: All TI-30X and TI-36X models (Any Texas Instruments calculator must have “TI-30X” or “TI-36X” in its model name.)" //@Anonymous: I am using a Ti-84 Plus CE from several years ago.

We disprove how the TI controls the market and had refused to buy one for a long time. On the other hand, I’m so glad that I ordered one a couple weeks ago. My 9th grader was able to use TI during his math test right away! I often pays just as much for a Cross fountain pen anyway!

with the chip shortage, this should go up in price even more. the chips inside these things probably 20 years old, who has that anymore?

Is this good for high school student? it seems too much for me. I prefer a simpler one.

for ACT test, you would need TI-84 plus CE:) //@anonymous: Is this good for high school student? it seems too much for me. I prefer a simpler one.

II know it has graphics but isn't this is "graphing" calculator?

I don't know how TI made the list of "qualified calculators for tests", but surely its a sweet deal for them. Year after year, high schools kids have to buy them. To me the tech on these calculators are kind of ancient, and any $5 app on the smart phone can beat it easily.

TI is a semi company, they have all kinds of chips. //@Anonymous: with the chip shortage, this should go up in price even more. the chips inside these things probably 20 years old, who has that anymore?
