I received the calculator before the date which helped my son for the test. He was able to take it school. The best graphing calculator I ever purchased.

I was looking for a calculator that did all the things that my TI-84 Silver Edition was lacking; and this is it. For less than the price of the TI-Nspire CX in stores, I got this TI-Nspire CX CAS graphing calculator (the CAS stands for Computer Algebra System). Now this is definitely not as powerful as a typical Computer Algebra System such as Maple, but it is the best option without lugging out the laptop. It can do many things previously not possible with any TI product and I have been very impressed with.
Also the backlit color screen is very much welcomed because personally I'm not sure why it took so long for a calculator to have this technology when mobile phones have had it for 5-7 years.

My only complaint is that it is rather difficult to learn how to use all of it's features (not that the product is difficult to use once you know how however). The instructions cover only the very basics and video tutorials online are few and far in between. Also the TI website offers nothing of the sort.

I purchased this calculator after a friend recommended it for the SAT, and I must say, it helped a lot! Even though it took a few days to learn all the commands and functions (and there are still some I'm just learning about a month later), the calculator was easy to maneuver from the get-go. I would just recommend taking some time to get used to using the calculator, especially if you plan on using it for a standardized test, because the keys and pointer section can take some getting used to, particularly if you're used to using a graphing calculator like the TI-84 or TI-85. Overall, though, the calculator's algebraic system, which is what I purchased it for, is pretty amazing! No complaints!

This calculator is easy to use! You can also find online tutorials for it easily. It is really great for college students and high school students who are taking SAT- AP exams! It also has a great appearence with it's color display!

If we compare the Nspire with say the TI-30XS purely on paper, it's laughable. The XS is puny in terms of functionality compared to the Nspire, no? Well, hold on there. While it is true that the Nspire can do things like matrices(!), differential equations, and 3d graphing, the XS is still faster at doing simple, simple arithmetic. So is the TI-84. The point I'm trying to make is: If you get an Nspire, make sure you still get a fast, lighter calculator for simple math.

I love this calculator, but I use it as my BACKUP calculator for studying.

If you are studying Algebra or Calculus, I suggest you get a non-CAS graphing calculator for your homework and for use during quizzes and tests, but if you want a fuller understanding of the material, use Nspire CX CAS graphing calculator for additional study in your subjects.

My main calculator for doing homework is my TI 84 Plus CE graphing calculator, but there are other good choices. Using it forces you to learn the material better.

The CX CAS model allows you to cheat, which is why I recommend you only use it for double-checking your work after you do it.

This is a great calculator. However, don't expect it to recognize natural log forms. It helps with calc 2 a lot, but I still use my TI-36X Pro more. Still a massive help.

The bees knees compared to the TI-89 Titanium.

**Summary of review** This calculator is awesome, it has gotten me better grades on tests, it was easy to transition from a TI-89. I highly recommend this calculator.

I am going through the math sequence in college right now. I am in the middle of the 2 year Calculus sequence then moving on to Linear Algebra and Differential Equations so I needed something better then the good ol' TI-89 that had been my go to for many previous years.

I am very used to the TI-89 Titanium and was unsure if I wanted to take the plunge of buying and learning a new calculator. I am SO GLAD I decided to give it a try.

Calculator is great with free overnight delivery which is why I paid extra more than it cost on other sites. However, it took several days before it arrived, which was a disappointment. I won't do that again.
