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

It makes calculus super easy. 10/10, absolutely worth the price tag.

I had to get this calculator for one of my engineering classes and it is amazing. It easily does pages of algebra in a second. And has great features for taking notes.

Definitely like night and day compared to the old TI I had

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.

Perfect item, just expensive

This is an incredibly powerful calculator, only really necessary for university level engineering or similar. I honestly wouldn’t recommend it for less than that because the menu based interface can slow you down and takes a while to learn. If you don’t need to do matrices of complex numbers in phasor form then get a TI84

This calculator has been amazing so far, a great resource while I pursue a degree in electrical engineering. That said, the software license is only for one year. Nowhere in the description is this mentioned. It almost seems as though they want you to believe it is perpetual, it is not and this does seem somewhat shady.

This thing is amazing, I cannot say enough good things about it. As an aspiring engineer, its important to be able to check the accuracy of my calculations, and this calculator does it all. Theres a bit if a learning curve but thankfully plenty of resources on the internet to figure out what you need to in order to execute certain functions.

I bought this for my son for his 1st year of college. He is now in his second year as an engineering student and it is still going strong.

I have owned this calculator for roughly one month, and it has been an extremely impressive product. First and foremost, this calculator has CAS capability. For those that do not know, CAS (Compute Algebra System) is an addition to graphing calculators that allows them to manipulate equations by variables as symbols rather than as numbers. This means saying goodbye to factoring, basic algebra, and quite a bit more. It can also integrate and derive indefinites, with weird answers coming up only here and there. For the calculator itself, it looks good, I have yet to drain the battery 30% even after one whole month of use. In addition, the mousepad feature combined with a dpad is pretty neat. While novel, it’s pretty useful. Then, turning to the document based side of this calculator. As with most of the NSpire line, you are able to create documents with various functions. For this one, it has compatibility with graphing, images, text, math, Python program, ti program, tables, and even more. All in all, this is a top of the line device, and truly a godsend for any and all engineering students in college. My one and only caveat, which doesn’t particularly apply to me, but rather to those converting from a Casio, I’d that this calculator isn’t very easy to learn to use to its true potential.
