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

Loved it

good

My daughter loves this for her studies! A+

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.

Clearly a refurbished unit, it had scratches all over, even when I paid for a brand new. I was thinking about getting it replaced but honestly I just want my money back. Definitely not worth it.

I like how the calculator has two ways of charging. It’s light and has color.

Graphing quadratic equations

Dura muchisimo la bateria, excelente calculadora.

Buttons could be less flimsy feeling, but backlit screen and easier to read than previous calcs makes for a win in my book

I love this calcultor
