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

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.

My son uses the for AP Calculus no problems

This calculator is easy to use with a good display. It works great for calculus and other upper level math classes.

Good product, wrapped in nice/new packaging as should be. All accessories included. Thanks!

Exactly what my daughter needed for college classes while in high school.

I really like it and it works very well. It is very useful too.

Amazing and reliable

A must for any high school student taking advanced math classes. The calculator is great and works great. My only complaint is its not an HP calculator, like I used in my Engineering classes when I was in college, but unfortunately this is what most teachers use nowadays. This is the third TI-84 PLUS we have had to purchase for our three oldest children over the last several years and they have all held up great.

An amazing product that exceeded my expectations. It installs programs easily and creating them is just as simple. The only flaw is that it cannot draw multiple lines at the same time, it must do it one by one on the graph.

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.
