I'm coming from a TI-84 Plus Silver/CE group of calculators. I impulsively wanted to get a new calculator and decided a TI-nspire was the way to go.Initially getting used to the different button layout was fairly difficult for me and calculating felt slow for this reason.One big con I have for this calculator is that I can't find a solution to accessing commonly used conversion operators like converting between rectangular and polar form for complex numbers without searching or typing out the expression manually (by adding "›Rect" onto the end, for example)A great solution I'd like to see is a favorites tab in the catalog, but for the meantime, having a notes page with your desired conversion expressions written out, then copy/pasting it into the calculator ... MoreI'm coming from a TI-84 Plus Silver/CE group of calculators.

Some great functions I've used lately were expand(), solve(), and approxFraction (). Expand can give you a partial fraction from an input expression, solve can be utilized for many things, but for me gives a fast method of finding intersection points on a graph. Then, fraction approximation can turn any number into a fraction, which can be fine tuned with a certain amount of accuracy to approximate, which I've made use of many times.Besides the main calculator, which is fantastic, I've also gotten to try out the TI Basic, Lua Scripting, and Python languages available. TI Basic has been great to use, besides some normal quirks it has like converting matrices or returning things in different forms (Using "Disp" is my goto workaround for most errors I get). Then, using Lua, it felt like I was trying out a beta test product, because I can't save scripts and it all just seems unfinished. Lastly, trying Python, I quickly found out that TI's implementation of Python was extraordinarily limited. I haven't been able to figure out a way to make use of it in any meaningful way, since you can't really call to a python script from anywhere besides the shell (and even this is limited).The last thing I tried out on this calculator was Ndless, which works great (make sure you're on OS version Ndless recommends). The main pitfall for Ndless is that most of the programs Ndless offers hasn't begun to support the CX II family yet.The biggest complaint I've developed is that I can't make my own hotkeys for functions, and I wish I could call to any program or script (including Python) within a calculator page.

I really love this calculator. I have the TI84 plus and the TI89. The only think I don't like about it is the buttons. I have long nails and big fingers LOL and sometimes it's hard to press the buttons but it is so easy to use. I really love it. I used it for my Steel class and it made calculations so easy. Programming equations are a breeze compared to the TI calculators in my opinion. I could never get my TI's to work right. I hope I can use it for the rest of my engineering classes because it definitely helped me with my Steel class.

Been using the NSpire CX for years now, best calculator ever. Just bought this and its the same with a few extras, no big deal. If the TI-84, or whatever people use, werent taught and used by everyone, so much that they are written into text books, these would be the standard. Cost too much money to rewrite millions of textbooks and retrain everyone though. So, these are a hidden gem. People say its difficult to navigate...its menus are identical to a computers menus. Open the menu and you choose which type of math youre looking for and the options are under that category, doc menu has identical options to a Microsoft word document. Really couldnt get any easier and cant recommend enough. I mean, it has excel built into it and it even runs rudimentary commands, and ... MoreBeen using the NSpire CX for years now, best calculator ever.

Can't ever go wrong with a TI-Nspire. I've used the normal TI-Nspire CX at school during all my 4 years in high school, so I've become fairly comfortable with operating it. But, I felt it was time for an upgrade, so I chose this, and I've got to say, best investment ever. As an engineering college student, this calculator really helps save time. With its CAS, solving integrals and taking complicated derivatives couldn't have been any easier. The buttons (arguably), in my opinion, feel very nice to click and make a satisfying "clicking" sound, which I like (compared to the normal CX). It has functions from solving systems, to analyzing statistical data, and you can even program your own functions using TI-Basic. All in all, this is definitely a must-buy for any ... MoreCan't ever go wrong with a TI-Nspire.

One thing to note is that this (and many other CAS calculators), are not allowed on AP math exams. Also, as I'm sure you've heard. graphing calculators are not allowed in lower college math classes either (ex: Cal 1, Cal 2, or even Cal 3). It is, however, allowed on the SAT and upper-level engineering/science courses in college, at least in my experience.
This is the one and only TI CAS Flagship calculator. It is super fast, has color graphing, has a track pad, and of course it has CAS = Computer Algebra System which does/handles symbolic algebra and calculus. It handles matrices, vectors, finance; everything you need in engineering. You can name your variables to your heart's content, unlike the TI-84 ecosystem. It is programmable! Did I forget something?
I had 3 of the previous generation TI Nspire CX CAS. One just died, but the two others are still working, well, one of them would get tangled up on really big calculus problems, and I'd plug the same problem into my other one and different graph.... that was weird. I bought this new TI Nspire CX II CAS back in April 2020 and even at first the Cursor Mouse Square Section under the display felt strange. It recently started getting intermittent, that is, the click up and click to the side functions were iffy. Today the CTRL button works once for every 5 or 6 pokes..... but can really appear completely dead sometimes. You know, this is my 4th one and only one of the things is working and reliably trustworthy. Texas Instruments sort of has a monopoly on the market and ... MoreI had 3 of the previous generation TI Nspire CX CAS.

Really, I store these things with the lid on and they don't receive any rought treatment. So when they break it is just because they started out wrong.
Shipping was on point and the package came in excellent condition. Battery came in at 50% but that’s ok because that’s the proper storage/shipping percentage, charging with any phone charger is good but charging with a laptop and the included application is recommended. Not gonna lie the CAS feature is the selling point for me since the calculator has more processing power to solve symbolic algebraic equations/ expressions compared the the calculator model without the CAS. New ti-Nspire users might need to get used to using it, I had prior knowledge on how to use it and overall I think it’s a solid calculator that has your back on all algebra and advanced mathematics classes.
I'm an adult engineering professional, not a student. Really like the CAS system that solves, simplifies, factors, expands, etc. algebraic expressions. No need to convert systems of equations to matrices. No worrying about silly mistakes in algebra. I really like that expressions can be variables, makes substitution super easy. I'm coming from a TI-82 (it still works!) so I felt fairly comfortable, but still had to watch a few YouTube videos to get the gist of documents and an overview of the features. Read the manuals, watch videos, google, etc and the fun and power slowly reveals itself. I installed the software, calculator comes with a license but you have to download from TI's site. Used the software to upgrade the firmware to latest version no problem, transfer ... MoreI'm an adult engineering professional, not a student.

Build seems solid, though not as rugged feeling as my old TI-82 which is built like a tank and survived many drops and abuse. Bought a padded case for this one, which I don't think is needed for the older models.
Im a math major in college and if youre planning on going into any math-based field, this is the only calculator thats a reasonable price and does EVERYTHING. My review for math people: I used this starting in calc ii. For calc ii, it does improper integrals, double integrals, indefinite integrals (the TI-84 doesnt do indefinite or improper). Pretty sure it can do some infinite series and sequences (but I think only problems that dont evaluate to a number?). In physics, I loved using an inspire because it will solve systems of equations (mainly useful for when I did kinematics). For calc iii this calculator will graph in 3D and you can plug and chug any formula. For diff eq, this calculator will solve them and systems of differential equations and it will give you ... MoreIm a math major in college and if youre planning on going into any math-based field, this is the only calculator thats a reasonable price and does EVERYTHING.

For calc iii this calculator will graph in 3D and you can plug and chug any formula. For diff eq, this calculator will solve them and systems of differential equations and it will give you exact answers, which most calculators wont do. For linear algebra, theres nothing better. Its super easy to select matrix size and do literally anything. The UI on this model is nicer than the previous model, but other than that theres no difference (I was using the previous model before getting this one). For non-math people: Ive seen a lot of high schoolers (or high school parents) buying these. DONT buy this calculator if youre in high school. I pretty much guarantee you wont be able to use it because it comes with CAS (computer algebra system). No teacher in their right mind would allow their math student to use one of these in classits just cheating. If you want something thats better than the TI-84 and have money to burn, get this without the CAS. Also, you wont be able to use any TI-nspire on standardized tests with college board (except I think AP Stats?). You can use the one without CAS on the ACT, but not this one. If you are planning on doing college math (beyond calculusthis isnt really useful until at least multi variable calculus), it might be worth the investment. There is a little bit of a learning curve, but Google will be your friend. Its really not as complicated as it seems. I found it way more intuitive than the TI-84.
Beautiful calculator - love the aesthetics of it. Great display. Actually like the separate letter keypad for typing, but I have not regularly used other graphing calculators that combine the letter keys as secondary functions on other, more standard, keys, so I understand those that have may be annoyed by this keypad setup.I bought this calculator more to have fun with it - yes, I guess I am a bit nerdy. I'm older and want to revisit Math, graph some equations, run some Statistics, do some light programming in TI Basic and Python (like the separate letter keys for this if I feel like typing out lines), take some notes, port and play some games - all in one hand-held package! And I can expand into learning its more complicated functions and features in the ... MoreBeautiful calculator - love the aesthetics of it. Great display.
