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

Is it the best graphing calculator out there? Not by a long shot! In fact, it's severely underpowered compared to the competition. But it has a few unique qualities.For us old timers, it's a spruced up edition of and old classic, the TI-83 Plus, which became popular because it runs on a Z80 processor (even if most people never took advantage of that). This popularity turned it into a de facto standard for students, teachers, and educational institutions. So if you're a student, this calculator is a safe bet. It will be accepted by teachers, even in most exams, and you'll have plenty of people around you who know it. In fact, some schools require this model. Ironically, the feature that propelled this calculator in the first place -- the ability to program it in Z80 machine language -- has been locked out by TI because it made it possible to cheat during exams. Even more ironically, this lock was soon broken, so they angered their customers for nothing. In place of the Z80, the newer models offer a trimmed down version of Python, as do most other graphing calculators today.While it occupies the low end of graphing calculators, in terms of speed and capabilities, it's still overpowered for just about anyone but those who do fairly advanced mathematics. Unless you're an engineer, physicist, or mathematician (or studying to become one), you won't come close to using all of the abilities of this calculator. But if you are an engineer, physicist, or mathematician, I would recommend an HP Prime G2, a TI-Nspire CX II CAS, or a Casio fx-CG50 PRIZM. All three are hugely faster, have more memory, and have CAS and better support for complex and exact math (on the Casio, the CAS is downloaded separately). If you need power, but are on a budget, the Casio fx-9750GIII is basically a black & white version of the fx-CG50, but at less than half the price of a TI-84 Plus CE. It's slower than the fx-CG50, but a lot faster than the TI-84 Plus CE.

Great for RECIPROCALS. This will be the best when calculating RECIPROCAL tariffs. You must understand value of reciprocals when calculating effects. Also great when doing problems where order of operations is key. If you understand LOGIC of math, you will get economic RECIPROCAL.Standard delivery made up deviation was applied to create a fake delay. Shipped from Calif and there was a weather delay! All weather events are on eastern and southern areas of USA. Had some boot charge for 1970 start up!

It really helped my kids with their math problems.

So after 3-ish years of having this calculator, I can confirm that it works for all my calculating needs and is still working without any issues. It is also quite durable in that I have dropped it a few times, yet I don't notice any issues resulting from it. The screen is still bright and colorful with no dead pixels or anything like that. HOWEVER, when I first got this calculator, it came with the screen "memory/REM cleared" and a tiny mark, if that makes sense. Regardless, this would be a five-star review if it mentioned that it was previously used/refurbished. This fact might be why it is offered for less than stores like Staples/Walmart/Target/etc. However, transparency is quite important; thus if you care that its refurbished or not, buy it elsewhere. Want to be more sustainable? Get it from amazon.

No major complaints, I use it for statistics and calculus and it handles just fine. Check if you can rent or borrow one from your school before purchasing! Also I would recommend turning the brightness all the way down to make the battery last longer.

What needs to be said! The TI device has always been worth the cost. My children used this brand growing up and now my adult grandchildren are using this brand in college.

Purchased for dual credit high school math; my kid uses is all the time.
