Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator with Student Software (PC/Mac)

The computer algebra system that comes on this particular calculator is a game changer. I’m a mechanical engineering student at Texas A&M university, and this calculator saved my a** last semester in thermo, mechanics of materials, and the electrical engineering class. Being able to solve a system of 3 equations with 3 unknowns in variable form is AMAZING! I know that there are websites to do this, but the cool thing is that you can use a calculator on pretty much any test, so you are golden! Stop wasting time doing math by hand, learn the functions of this calculator and save your head from being repeatedly thrusted into a wall when you make a stupid algebraic mistake!

This calculator is awesome. It has issues doing some things that you could do with Mathways phone app, but this calculator is still amazing. I use it for my calculus class and it has the ability to solve Limits and Derivatives. Even if youre not doing hard math with it, if youre willing to learn how to use the calculator id recommend. The UI is kind of overwhelming admittedly so be mindful of that.

Got this for my son who needed it for high school and college calculus classes. Many schools provide these as loaners for students as well.

You can use this on the SAT! It’s so nice, and it works really well! It can help you solve so many problems way easier, and overall it’s such a unique and cool calculator to just have! The touch pad blows peoples minds!

I am going back to school. From my previous college days, I was using a TI 82. This is much better. The screen is easier to see and it give answers in easy to use format instead of just giving a decimal answer. This has, however, caused me some issues on several math tests. If the majority of the problems you are working on will require a decimal answer, change the setting to approximate instead of exact. If you dont change that setting, you can still get a decimal answer by hitting [ctrl] [enter] instead of just [enter]. If you do hit [enter] then try to view the decimal answer by hitting [ctrl] [enter] be sure to check the screen to see what it calculated. Sometimes it repeats the last calculation on the formula you are using so instead of a numerator divided by a denominator it gives you the numerator divided by the denominator divided by the denominator. You just have to verify what it calculated. I am still trying to figure out the Documents feature but overall, I am extremely happy with this calculator. If there is a drawback with this unit, it is in the documentation. They could have provided more examples of how to use the features. I am using YouTube videos to cover what I still need to learn.

Once you get used to how this thing works, its really amazing. Its valuable in that you can define functions that could be tedeous and then just enter some values to calculate. i.e. herons formula. The stats features are very nice and its more calculator than most people will probably ever use. You can program Python on this thing! Basic programming is very straightforward. The screen is nice and colorful. You can save notes in it with geometry figures for reference if needed. It comes with computer software that you can install with the same interface as the calculator itself and then transfer your documents to the calculator. This way, you can type your notes and test out functions prior to transferring them onto your calculator which is much more efficient. Overall, the learning curve for this calculator is much steeper than the TI-84, but the features blow the 84 out of the water.

This may be the best calculator on the market, it definitely wasnt for me though! I figure it is more for programming than mathematics but I may be mistaken. The full keyboard served no purpose for me. I did not like the rocker type buttons for common math functions. I didnt like the scratch pad or the software layout. The keys were nowhere near a TI normal layout. I could go on....... Im a TI fan, been using them since the 90s but this one was not for me. I sent it back and replaced it with an HP Prime. Hopefully itll be a better fit for me.

Awesome calculator will do just about anything you throw at it. Interface is ok, on par with other TIs. Its just a matter of finding out how to do something. The main menu is a little awkward. Need a touch screen as the curser is archaic. Need 2nd entry shortcut. Great once you get used to it, but why not make it more intuitive. Dont know of a better calculator...

I dont hate it but prefer the TI-84CE.

Review for the Texas Instruments TI-Nspire CX II CAS Pros: Its a calculator that does algebraic equations. Great battery life. Cons: Everything else. Imagine having to spend double the price for something you already have thats worse in almost every single way. If this wasnt required for school Id just use an app (mathways, desmos, etc) or literally anything else. The mouse pad function is literally the worst Ive ever encountered. The shape, response and feel and click are horrid to use. The build of the entire unit is bad, the plastic feels cheap and the charging connector is over twenty years old (mini-b) so prepare to buy another cable or an adapter to use it with any existing chargers you have. Theres no touch screen and all of the buttons feel loose. The operating system isnt intuitive either. If you want to study for hours so you can figure out how to use this to study for hours, this cheap, hollow feeling plastic is for you. I can buy a cheap smartphone with more power, newer components, better build quality, several forms of wireless connectivity, an IPX waterproof rating, thats also compatible with my existing charging cables, that does an infinite amount more than this calculator. Lets not forget that this is Texas Instruments top of the line unit that came out on July 15th, 2019!!!. Let that sink in for a sec. Youre paying anywhere from $150 USD to $250 for a thing that in every way is worse than other options that are available to you, that are cheaper, and more robust with far more reusability and durability. Also, if you buy it new you get one copy of the digital version of the calculator. If you happen to have a computer at home and take a laptop to school youll have to pay the full price on the second computer (currently over $100) since they dont offer additional device pricing, like most software companies have, and good luck finding any information about pricing online. Its not even listed on their website. If you can find it, go with the HP Prime Graphing Calculator. Its discontinued, better in almost every way.
