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

This calculator is amazing! This product comes with a key for the software to be installed on your mac/windows device as well. The calculator is incredibly powerful for graphing in 2D and 3D. I would easily recommend this calculator for anyone that is trying to self-study math or is reviewing concepts. The computer algebra system (CAS) is quite powerful. I see many students relying on this to do their homework in the calculus sequence... I would not recommend students who are currently enrolled in new math classes to use this calculator as this CAS is too tempting for most students to constantly use. The ability to program in python is really cool, but in all fairness most students program from their computer but save the file to the calculator so it can be read later. I love this calculator and would recommend this to pretty much any student in his or her junior or senior year. Most math classes in these years wouldnt need this functionality, but the CAS can help validate the logic of these students.

This is obviously a very capable calculator which is why this gets 4 stars, but there are 2 things that I cant believe passed quality control. First one, when the calculator sits with its back in its sheath on the table and you type it will rock back and forth. I have a cheap Ti-36 that does not do this. My friend also bought this calculator and has the same issue. Second is it only lets you type super slow otherwise it stops recognizing the input, once again my dirt cheap Ti-36 does not have this problem and can accept a far higher input speed. For the money and given that this isnt the first iteration Id expect fundamental things like this not to be an issue. Also really not a fan of the baby blue as the only color option. Mathematically, no complaints, but thats to be expected, this is the top tier calculator. Also needs a higher res screen, its 2019.

I bought this for quite a lot of money, and when I tried it out, it had a lot of advantages and features. It has a notepad for writing whatever you want (you can even put math on the notes), spreadsheet, graph, statistics, and geometry. Theres even DataQuest, which I dont have the resources to use it, but if I come to a college, and I have a math or science class that uses it, then Ill be more happy to try it out. I can even play games (and yes, you can use an emulator to play NES, SNES, GBA, etc., but you need to install an app called Ndless for the TI n-spire CX II CAS (or whatever n-spire you use)). The battery lasts a long time without plugging it in. The good news, is that the calculator comes with a tutorial, on how to use the calculator, called Getting Started, (and also Getting Started Python) in the Browse option on the main menu, in a folder called Examples. I suggest trying it out. It even comes with something called scratchpad, where you dont need to create a document in order to perform quick calculations and graphs; you can just do it directly on the scratchpad with the press of a button. Great calculator, I recommend it to a college student, and/or whoever wants some high-tech for calculating stuff!

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!

My kids needed this for school, good price and arrived quickly

I was a loyal HP-fan for 34 years, starting with the HP28s back in college. As an electrical engineer, I progressed through several upgrades up to the HP50g. Then I got the HP Prime, and at first I hated it, so ignored it for almost a year. But then it grew on me, and I kicked myself for not adapting to change sooner. But, there was always something annoying about the Prime, where for every convenience, there were almost two inconveniences. Then I decided to try the TI CX II CAS Student Software trial for 30 days, and I was blown away so I bought the calculator from Amazon! Why, oh why, did I torture myself with HP for so long?!?! Nearly everything about the TI is easier, and despite looking student-centric (which could be interpreted by some as a toy), I promise that this will be your work calculator. The document-based interface is exactly what I needed - I rewrote my HP applications for TI, including a few new ones, in a fraction of the time (the language is easier, the editor more intuitive, and the dedicated keyboard destroys HPs multi-click, illegible color scheme, keyboard). I wont bother looking at HP anymore - Im sticking with TI. There is no way to describe the experience with this calculator here - just buy it and if you dont like it, return it (but you wont!).

This is the ultimate calculator. I used to have a TI 84 Plus CE but once I hit Calc 3 it no longer was able to keep up with the level of math concepts I was being taught. This calculator has so many available functions and the ability to simply type on the keyboard makes it even better. Totally worth every penny.

It has really saved me when it comes to class but the learning curve for some of the advanced functions is steep.

I despise this calculator. As a point of reference, my favorite graphing calc is the TI-89: the terminal-like interface woven into a sorta-windowed OS was perfect. The N-spire is the antithesis of TI-89: I have to make a new document to do anything beyond scratchpad calculations, which only seems justifiable as a method to prevent the calculator from becoming a gaming or cheating device by removing ALL flexibility and ignoring adult users who dont take standardized tests and can game if and when they please. This forces professionals like myself into this pedantic and arcane document system, so we cant just eg. write a quick function and use it flexibly if and when needed. Instead, everything is a laborious set of steps to follow; Even writing functions on the scratchpad is tedious because it only offers half the screen for editing!! Further, I think tokenizing everything is ridiculous and unnecessary; Where variables and functions end up being saved is completely opaque; The touchpad moves the cursor when pressing or tapping to select; And while Im not adverse to thoughtful and functional changes, I dont see why the placement of nearly EVERYthing had to be revised from the TI-8x series: Im CONSTANTLY trying to remember the six or seven steps required to do something that was only one or two steps max two decades ago. But the final nail in the coffin: dedicated ALPHABETICAL keyboard in a region (North America) where EVERY device with a keyboard has Qwerty (and most have touchscreens)! This really feels like a device created by educational elitists that dont realize (or have forgotten) that calculator games were a gateway to a lifetime of programming for an entire generation who now make the devices and apps enjoyed by billions.

Works perfect for our needs
