Texas Instruments TI-84 Plus CE Blueberry Graphing Calculator

Ive got the 82s, 83s, 85s and 89s all sitting in a basket waiting for the grandkids to need them. But the internal batteries died! Who would have thought that storing them for 20 years would do that? My daughters 89 is still working great but thats because she uses hers daily. In any event, the grand wanted a blue graphing calculator that has games on it. Hmph...they didnt have that when I was a student! Hes enjoying this calculator immensely. As with all the other TI calculators, this is a quality product.

Overall excellent calculator

works very well and came in the package with everything. the price is quite high since it is the newest most (at this point in time) but it will last a long time.

Not to easy to use at first but it came with all TI84 for Dummies which I love!! The color graphs make it so easy to read and the battery life is great!

Ive been a fan of TI calculators since the early 70s, when I bought my first scientific calculator. My daily driver is a TI-Nspire CX ii CAS. Ive had an HP Prime and a Casio fx-cg500, all CAS calculators, but the best is the TI. As for the TI-84 Plus CE - I really like the looks and the colors; I just had to have one. Sadly, the functionality does not live up to its looks, and certainly not its price! The scientific functions are about the same as would be found in a Casio FX-115 ES Plus for less than $20. To be fair, the 84 has some great statistics functions. But lets get to the graphing. The TI-84 Plus CE has a very nice, large color display, but in graph mode, the graphing area is significantly reduced, as are the graph analysis tools - most of which are missing altogether. Come on TI, this is near your top of the line non CAS grapher and it is no better capability than a $39 Casio grapher. Speaking of things missing, where is the backspace key? The line editor is in character overwrite mode by default. Editing a previously used equation/expression is a pain. This is turning into a rant, so Ill quit. It is clear that TI designed this calculator specifically for high school students and to fleece said students/parents out of some serious bucks! At best, this is a $50 calculator and performs like one. Ill end on a positive note - connecting the 84 to a PC using TIs free TI Connect is easy. The 84 is programmable using TI Basic and assembly language. Ive not tried the latter. The TI Connect software contains a programming editor, although programming on the calculator itself is not difficult for short programs. If you really like programming your calculator, this is a good choice. There are tons of programs, so peer to peer support is good. The bottom line is that if you are going to pay this kind of money for a grapher, then buy the TI-Nspire CX II CAS. Its 3 times the calculator and the best out there.

Does what its supposed to but the battery died about 6 months after purchasing the calculator.

Great product great for high school student / arrived 4 days late

Great product and beautiful color. It was just as you described. Awesome service, thank you.

This is a great price on this calculator. These are extremely durable. The different designs and colors keep my boys from arguing over whos is whos.

Its kinda expensive for a calculator but its good quality and needed for my school
