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

Im 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. Im 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 TIs site. Used the software to upgrade the firmware to latest version no problem, transfer files to and from calculator, and the software emulates the calculator so you can use your computer for editing, screen sharing, etc. All very cool. 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 dont think is needed for the older models.

A handy tool for college maths and stats.

I’ve used TI calculators for about 25 years, from the 30 to the 84 to the 89 and now the CX II CAS. All of them were fantastic for their time, but those who want to get the most out of their calculator in 2022 should go for this one. Specifically it’s best for people who need to do calculus, physics, and engineering. Those who are only in algebra courses may be better off with the new TI-84 Plus CE. The CX II CAS is well designed and easy to use. It’s surprisingly thin and lightweight. It charges with a mini USB cord and last for at least a few weeks of regular use which is amazing. Calculations are very fast, and it has some tools like spreadsheets and python built in, but these are pretty clunky compared to using a computer. I’m not sure why someone wouldn’t use a computer for that anyway. It also comes with a free copy of a virtual calculator program you can use on your computer. I’d recommend this for any math, physics, or engineering college student, or possibly high school as well.

The learning curve is a bit steep if you are not familiar with TI calculators but the payoff is worth the effort. It does most everything you might want to do in mathematics. From algebra to xyz plots the TI-Nspire CX II CAS color graphing calculator will do the job. It is light weight and the keys are easily accessible to larger fingers. The screen is a good size too and easy to read. However, it would be helpful for older eyes if you could enlarge the mathematical text. You can enlarge the document text. I graduated from the TI-84 Plus, and I am not at all disappointed, in fact, very happy I did.

Took a while to learn the interface and all the features, but it is a great calculator and saved my life in calc. The notes feature is very helpful and the quality is great!

This is a very powerful and professional calculator. I have been using the TI84 since middle school, and now that I am almost done with college (majoring in mechanical engineering), I thought it was time to upgrade to a more powerful calculator, and I can say that I am very impressed with this calculators abilities. I wish that I had this going through all of my math classes in college. Getting used to the keystrokes is very difficult and will likely take years for me to feel as comfortable as I do currently with my TI84, but it is worth it. I highly recommend this product for someone that is in advanced mathematics (Calc, Lin. Algebra, Differential Eq, Statistics, etc). I would not recommend this to someone in middle school (and maybe even high school) as this is a very advanced calculator and a lot of its features wouldnt even be used by a middle or high schooler. I hope this helps.

If youre hoping to jump up from the Ti 83/84 you may have used in grade school to this thing, well its nothing like those calculators. The user interface is very picky and the mouse isnt the best. The calculator does all kinds of stuff but good luck figuring out how to do it, Even plotting a graph from points and tracing it requires going through a couple windows. I couldnt just pick up the Nspire from the 83/84 and figure it out. Ive been having to watch multiple videos and reading the manual to figure it out. Its obvious this calculator is capable of a great many things but figuring it all out will take a while. If you dont need all of these features maybe look at something more simple.

Es un excelente producto para aquellos estudiantes que pueden usarla como herramienta. La recomiendo para ingeniería y ciencias exactas.

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.

Its intuitive to use and after 2 days of practice you can get around it. Keep the booklet handy for when you need to remember how to do some more exotic stuff. You can create and edit python scripts on it ,from the device ,and the python library has all you need. Doesnt have 3rd party python libs ,but you can add them or copy the files. This python capability comes in handy if you need to roll your own stuff to help you. Build quality is good and it doesnt feel like cheap plastic.The battery seems to be accessed by unscrewing the back lid so this should make battery replacement easy. Quite nice mini computer to have around to help you.
