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

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

Awesome calculator. It really helps my daughter with her school work

This thing is incredibly cheaply constructed and plasticy! The interface is ridiculously non-intuitive and the buttons barely work. Trying to use the touch screen is nothing if not nearly impossible. I had a TI-86 that worked great for over 20 years, and this thing is truly garbage by comparison. I would also like to review the reviewers of this product because I see this again and again. I couldnt understand how anyone could give this pos more than one star, so I looked at the four star reviews...The vast majority of people have really negative stuff to say about this pos, but they still gave it four stars!!!? People: you really need to grow up and give star ratings that reflect what you say not rate something high because psychologically you dont want to admit you got ripped off!

So listen to video to get tips n shortcuts. Slight learning curve when using for exams, just make sure it’s deg or rad n the right sig figs! Also, your 2 fingers can enlarge the graphs! Lol. Currently, using for AP chem n AP calc.

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.

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.

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

I bought this for my Middle School son who does enriched math. I was going to get a TI 84 CE color calculator and this was the same price so I figured this was the best deal and he could use through high school. The teacher borrowed the calculator to learn how it worked so she could help students and basically gave it back and said she couldnt figure it out. My son still used it though and figured things out on his own but I thought that was strange. Unfortunately it got stolen in class. So keep an eye on this thing and make sure you write down the serial number. I think you can only find it in the menu system. I took pictures of the calculator when we first purchased and looking back there were no markings. If your looking to purchase this over a TI 84 Plus CE, I would have to pick the TI 84 Plus CE even though it may have fewer features. Unless the schools are supporting the Nspire, there is no point in getting one of these.

This is the best calculator I ever purchased. The battery life is top-notch as I have used it for weeks on end without worrying about charging (keep in mind I dont use it everyday/ all day). The ability to learn how it functions is relatively easy. Operational videos on 3rd party sites will definitely provide you with the necessary insight. Lastly, the interface is okay as it can be overwhelming for someone new to the TI Calculator series.

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