Customer Ratings & Reviews

Needed for school works great. It does everything I needed for my statistics class.

This was not all that useful to me at all and didn't have what I needed but I'm sure it's a good calculator.

If you need to get a TI scientific calculator, might as well get this one. They're pretty much all the same.

I originally got this back in high school for the SAT and AP Tests that allowed calculators, and never looked back. Compared to the TI-84+ this does everything. There are only 2 cons as far as I can tell, and that is you can't use it on the ACT (which requires the TI-84 but has way easier math problems anyway) and certain college math departments prohibit them. I went to one such college and every math teach I ever had I walked up to the first day and asked for permission as long as I showed my work and they were all fine with that. I'd have to rate this the best school supply I ever purchased considering it's allowed pretty much everywhere, and if you are taking physics often required, I've had mine for 11 years now and it still works. Only put it away once I was forced to use my company software. TLDR You can use this on the SAT, AP TESTS, and 99% of college all for less than the cost of a textbook.

I received this product summer of 2005. The capabilities of this product is seemingly endless! When it comes to math, this calculator far exceeds the capabilities of my old TI83+. It can solve your calculus problems in a jiffy, and it has the ability to do enough math functions to satisfy a high school or college student. If there is anything lacking, there are websites where users can upload calculator programs and games. The battery life on this is simply amazing, I recharge my batteries perhaps once a year. Now that I am no longer taking math, I use still use my TI89T as a calendar, and note taker. It also stores all of my phone numbers, which came in handy when I switched cell phones. In other words, this calculator can do almost anything you want it to do!

This is an amazing calculator that is capable of performing most advanced calculations. Can be used in conjunction with an optional USB cable in order to upload data points and programs. This has same functionality as TI-92 minus the full keyboard. I had no problem using this calculator on test or exams, but I would recommend checking with your Professor/Teacher prior to purchasing.

The beauty of this calculator is its symbolic capabilities. It can integrate/differentiate and perform standard operations symbolically. I use it for my mechanics classes and upper-level math courses and 'til this day has not brought me down. Compared to the Ti-nspire, you don't have to charge it, the body is far more rigid and robust, and most significantly (imo), it feels like a calculator!

I purchased this after giving my TI-83 to a sibling. This calculator is light years ahead of the 83. The screen is sharper, there's more memory for storing programs, and there are many more functions than my old graphing calculator. The TI-89 has helped me so much with my college calculus & physics courses. Texas Instruments has really outdone themselves with this.

The price should keep most people just looking to add and subtract away, but if you're in calculus, this is the one for you!! Features FAR beyond the TI-84+, and better screen resolution and battery life. I used this one for three years in college. GREAT calc! Good investment for students, I still use mine!

its obvious the newest origional calulator out there great for AP classes it me through trig and calculus its hard to earn every feature at once there are so many very hard to download games

I bought this to replace an older model TI-89 that was no longer working. I use this for Calculus and Physics. It has some different features from the older TI-89, but I was able to use it for my purposes straight out of the package without having to look at the manual. I do think that these things are a bit overpriced. I was also not crazy about the curved layout of the keypad, but I am getting used to it. I do not like the home screen, and I think that after all these years, the screen quality could have been improved. I like the calculator, but I am rather unimpressed. I would never have upgraded if my old one had still been functional. I just needed a graphing calculator that could do integrals.

I bought this few months ago, and im using it for my calculus class, it is hard to use(because it is very different from other graph calculator) but once u know how to use this, there is nothing better than this calculator for math class(higher than calculus)

While there are a few super-premium ones above this one, this is the best, most practical everyday graphing calculator I've found. I use it for business math, some linear algebra stuff, and stats. Works great for all three. I use it at work and at home.

Great aid for those taking higher math courses. Takes I believe 4 double a batteries which last quite long. The screen is large enough for easy viewing and once you get used to the calculator, you will know it by nature and will become a powerful tool.

This calculator is an Engineering sutdents dream. This is helped me so much through out my studies. Check your anwsers, check the soultion, graph the soloution. Its great.

Great features and somewhat easy to use. But I will say this for any students: I made it through all of college as an engineering student without ever using one. If you're good at math you won't need it. If you're bad at math it won't make you any better, it's just a crutch. Half the time you're not allowed to use fancy calculators during exams so your crutch has now ruined you. They also open up the door to cheating since you can write and store all kinds of things in them. If you're dedicated enough to read the instruction manual on how to use the calculator and then spend all that time writing your cheat sheets into it, just learn the material to begin with. you'll feel much better about yourself when you do well in class.

This is my first graphing calculator and I have to say I'm impressed. This thing can solve matrix algebra, linear equations with large degrees, graph multiple points and find the vertex for the equation, simplify. Just simply Excellent.

Great graphing calculator for the price. SAT Approved. Great for all classes in High school and up. Very reliable and the customer service is great. If you have a broken screen, they will replace it for free.

I purchased this for a class I'm taking and it really simplifies solving equations. Has a lot of capabilities that were not available a few years ago.

The best calculator to buy. Worth the cost, and lasts long.
