Oh that’s neat! Probably should’ve checked your link. Not sure what the advantage of the Ti-84 would be for highschool math, but the UX on NumWorks calculators is completely a game changer, especially with stats and graphing questions.

Maybe everything is possible on the Casio, but it’s so much clearer on the NumWorks (especially for eg. Physics questions, where you might want to retrieve values you calculated earlier with full precision, etc). Genuinely felt like a cheat code when I was in highschool. I showed mine to my teacher and they swapped the whole’s schools standard calculators from the Ti-84 CE to the NumWorks, which is cheaper too.

I mean sure. Unlimited precision calculation I don't think is the proper domain of the cheap desk calculator.

I mean what do these do? I think like 10 digits worth?

If you're actually doing something requiring over 10 digits of accuracy and you can reliably hit that you probably have a $10 million lab...

So honestly what are we talking about here...If it's pure mathematics this is a bad tool for that as well.
