Texas Instruments TI-84 Plus CE Graphing Calculator, Matte Black

The Texas Instruments TI-84 Plus graphing calculator has been great for my teenage son that is doing high school AP classes and college courses. This calculator was approved for the mandatory state high school exams and college exams for Florida. My son has owned this calculator for several months and has not complained one time about malfunctions. I felt I paid a little too much for the calculator, but it was way cheaper than other brands on the market.

This item is great for school and algebra. I got the Infinitely Iris color. Definitely recommend. I will be using it for the years to come!

Fantastic calculator. I had the TI-99 but it was actually too complicated. This is one step down but added color. The multiple colors on the graphs helps considerably. I am an adjunct professor at a local University and use it for both my Modeling Algebra and Pre-Calculus courses.

My high school daughter's Pre-Calc teacher recommended this calculator for her students. It arrived about 75% charged, and my daughter has been using this week in class and has not had to charge it yet. It comes with a rigid plastic cover that slides off the front and can slide on the back for the time that she is using the calculator--I love that! My daughter was delighted to see that it has the periodic table on it--could be handy for Chemistry too.

This gold standard calculator was on sale here and cost barely more than the TI-84, so I had to jump on it. There was a nice magenta color which my daughter would have loved, so I thought I selected it. But when I picked it up, it was black. Disappointed, I realized that all the various colors had the exact same SKU and webpage. In other words, you have no control of the color. I think this is a bad business decision for Walmart. No one wants to be surprised like that anymore, in this day of computerized inventory. Just list the exact color, or else there will inevitably be some disappointed customers who hoped it would be one color or another.

I did not receive the correct calculator!!! I got the PYTHON instead of the one described and pictured!!

If the description was clear that the package had been open and the price reflected that fact, then this review might have been different. However, since the description was unclear and the packaging was greatly disturbed, I could not be sure that the calculator was not also damaged so I returned the product. This review is no reflection on the model of calculator itself. This calculator is the standard. However, I cannot recommend this seller and am skeptical of 3rd party sellers from this platform.

The calculator didn't work. Kept blinking an error. After several hours watching videos and reading Reddit threads, I determined the battery doesn't work. I also learned that Texas Instruments will send a free battery and ordered one. It was to be here in 5-7 days. It's been 9 days and it looks like it's scheduled to be delivered 2 days from now. I will be out of town by then so it'll sit in a hot mailbox. This was needed for keystone testing which has now passed. Thankfully, the school had enough for her to use theirs. IF you buy this, make sure you buy it ahead of time. I'm sure it'll be great if/when we get the new battery.

Inside Package was water damaged. I returned to the store and am waiting for a refund.

Did not work on arrival. Will not charge and cycles through a loop of “validating os” and “restarting.” We tried a hard reset and replacing the battery but ended up returning.
