Texas Instruments TI-84 PLUS CE Graphing Calculator, Black (Frustration-Free Packaging) (84PLCE/PWB/2L1/A)

Dura muchisimo la bateria, excelente calculadora.

It was scratched, but I think thats because it scratched extremely easy. I was cleaning it and I think that it got more scratches. And I was cleaning it with a microcloth. Everything else works fine. The screen is fine and the calculator works as expected. It comes with a case, charger, an adapter USB to USB. It comes with a manual as well.

Great product for advance maths, calculus etc. Very happy with the purchase

Fast delivery. Very satisfied! Thank you!

I am a Math tutor. I do not use calculators ordinarily, except as a teaching tool. Love the graphing. I use the different colors for explaining transformations in quadratic equations; all on one graph. Students have an epiphany, when viewing this.

Great battery life, love it so much, worth the $120

Satisfied.

overpriced

While solving quadratic equations with substitutions I had following problem. 9(216^2/3)-53(216^1/3) comes out to 6 as expected, but 9(216^2/3)-53(216^1/3)-6 comes out as 2e-11. Even doing 9(216^2/3)-53(216^1/3) solving then doing ans-6 produces 2e-11. It was already a slap in the face I had to buy this stupidly over priced calculator and cant use my phone, but to have it be this expensive and not even work right is extremely disappointing. I have only used it one day to find this problem and Im sure it wont be the last one I find.

Bought this calculator in used/good condition. Calculator arrived all scratched and extremely dirty.
