Well Casios are better than TI calculators. My current favorite calculator is Casio ES-115 PLUS2 https://www.amazon.com/Casio-fx-115ESPLS2-Advanced-Scientifi... I like it because when you enter sin(pi/12) you get (sqrt(3)-1)/(2*sqrt(2)) in mathematical notation, which is really nice for a $16 calculator. Here I'm going to hurt TI: If you need a TI-84 or TI-89 for school, the place to get them cheap is shopgoodwill.co…

TI is pretty clearly just coasting on being the one mandated by a lot of schools; there's no way you can justify them still costing like $100 and having the same capabilities as when I was in high school.

The new ones have rechargeable batteries, color screens, USB, and Python. So, only a decade out of date.

I searched for graphing calculator apps on iOS the other day and found a ton that simply attempt to recreate the TI-84, e.g. [1].

So anyone with high school kids: are they still buying $100 physical calculators? Or are they just using free/cheap apps?

"This website is hosted on a Casio..."

Not anymore it isn't.

I'm a few years out of high school, but during my time anything other than physical calculators were explicitly banned due to the potential for kids to be accessing the internet during exams. I even had a friend who won one of TI's higher end calculators at a math competition, only for him to be banned to use it during exams because of its higher capabilities. Perhaps things have changed in the post-Covid world.

Just graduated secondary school in April. Just as a someone said in a reply below, anything other than a physical calculator is still banned during assessments. There are tools like Desmos, GeoGebra, etc... that may be used by the instructor and students during lessons though. Although it's strange, there is no explicit rule provided by our Mathematics faculty that bans higher functioning calculators I've only seen one person carrying one.

This calculator got me through college. I then passed it down to my brother and it lasted him through college also.

Time for your brother to consider setting up a webserver on it! /s The TI 80 series were more popular in my college days, perhaps these Casio's were more popular in another time or region?

I think Casio calculators are quite popular in the UK - I used an fx570 through secondary school and university. It was the one recommended by my school, and then it was one of the three models (all Casio) allowed by my university[1]. I briefly had a TI83 for A-Level Further Maths, but I didn't use it much.

The fx-9750 would have been usable at secondary school (though it's more powerful than what you really need), but it wasn't on my university's allowed list.

[1] Currently you can use an fx 991, fx 115, or fx 570 for CS, and I pretty sure the list was the same whilst I was there - https://www.cst.cam.ac.uk/teaching/exams/calculators
