Decent deal! It's not a graphing calculator and depending on your school, some teachers use a specific brand or type of calculator they recommend (depending on the classes). As a math teacher, I generally recommend TI-30XII's; however, this isn't a bad casio version of the same thing. There are SOME that require a bit of learning in how to type in say 5cos(30) has some casio's going : 4 x 30 cosine button equals equals in order to calculate.

Thanks for the link to other colors.
The product description looks slightly different from the OP. But do you know what's the difference between the "Plus 2nd Edition" and the "Plus B 2nd Edition" ?

I kind of miss having a calculator around. I had an HP 15C for 30ish years then I realized they'd so gone up in value, I'd be crazy not to sell it.

This looks like it would do way more than I need for a cheap price...

At some point, I had to re-take the SAT as I was going back to college (and my scores were too old to count, going back at 50!) and I got a new calculator, but I took it back to the store for a price adjustment (it'd dropped from $25 to $12 or something) and they were giving me the run around, so I think I just returned it.

Maybe it was on clearance, and that's why they wouldn't adjust, but it seems like I'd have just taken the money and gone to the shelf and bought a clearance one. I should check my desk and cupboard, maybe I have an old one (still new in the plastic) somewhere...

The plus is the battery plus solar panel.

The "B" uses a single AAA battery, while the non-B (the blue one) has a solar panel with a backup LR44 (a.k.a. AG13, DR44; coin style) lithium battery. I have the non-B version that I bought in 2022, and haven't had to mess around with the battery yet. If I had the choice, I would probably stick with the solar/LR44, since this version is already thinner than a AAA battery, and the AAA will make it thicker/bulkier.

I really want a graphing calculator at this price. Graphing calculators stalled, and haven't gone down in price in decades while everything else electronic has.
