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...

TI is like the Intuit of the education world. I want to love them but this is ridiculous - a N4120 celeron laptop is the same price as this new calculator - it might be a garbage laptop but it's doing a heck of a lot more for your $160 than this calculator is.

Genuine question, who uses these in practice? In my experience, calculators beyond the basic were always banned in high school and college, cause everyone's so afraid people might store something into them, and afterwards it's just matlab and python. It's not like laptops aren't a thing that everyone has on hand.

Electronics engineer here. I use my HP Prime G2 daily in the lab for basic things as well as quickly calculating complicated stuff, since you can pretty much program it to do whatever you want.

You might say why not use Python or Matlab?! It‘s true that you don‘t need a small handheld device to do engineering calculations where there is a ton of other much stronger and free options out there. But the thing is, a calculator is a pure dedication to one thing. You turn it on, you do your calculation, get the answer and move on. It gets out of your way. Plus it is a better feeling to type stuff using the dedicated buttons in a calculator than using a keyboard.

The contrived ones where they make you graph stuff, but that’s about it.

Ti really needs to stop with the artificial product differentiation. There's no reason 15 years after the Nspire CX CAS came out that everyone of their calculators can't do CAS.

CAS capabilities are prohibited in the SAT: https://satsuite.collegeboard.org/sat/what-to-bring-do/calcu...

Wow, they used to be allowed back when I was in high school. It came in super clutch for SAT but much more importantly AP. Our school mandated the original CS CAS and drilled us on how to use it effectively and I got good mileage out of it through high school testing and college.

I lost it at some point and got the version 2 and I would occasionally use it for work. I wish it had USB-C because who has a mini-B cable for charging these days

Earlier quoted context omitted.

For a $10 BoM and maybe a year of R&D I would say that $160 is bad.

Their engineers are still trying to figure out how to make backlit keys. Just give them another two decades, I'm sure they'll crack it.

The $0.03 LED, $0.04 diffuser panel and the extra 3 cents for manufacturing keys with transparency will eat into their 93% profit margin. Can't have that. The children will just have to use a desk light.

You may have gone to a poor high school and college. I saw plenty of calculator use in high school and college a long time ago.

Poor? In what sense? I graduated a few years ago (in Europe) and I think I could’ve gone through my entire education without owning one. Math, for me, went from nice numbers to ugly numbers that you had to do by hand (because that was the point), then to just letters and squiggles.

At no point was there a need to work with hard numbers or to learn to work with a physical calculator (I haven’t seen one in the wild in years).

International Baccalaureate math has some stats questions that require a calculator that can do stats questions. Not really possible by hand in exam conditions!
