Best Graphing Calculator Ever!!!! By far the best and only calculator I will use. Out standing performance. After using this calculator throughout 10th grade Algebra II, I thought I might as well get around to writing a review of this newest TI product.

The Pros:

Elegant and efficient solver screen. This calculator does everything: it solves equations, matrices (in pretty print, no less), factors, solves systems of equations...just about anything you ask it to. I could *almost* use this calculator exclusively in algebra class and sleep through the lectures. The only problem I ever had with it was when I wanted it to "complete the square;" a rather obnoxious process in Algebra that takes forever to do by hand. The prevalent pretty print is nice, and I agree with the reviewer who said that parentheses errors are a thing of the past with this calculator...as well as fractional errors, radical errors, order of operations errors, etc...

My son lost his and we bought it a second time. His professor walked into the classroom two weeks later and said someone forgot it. Now we have two of them. His first one is two years old and still works great. We are pleased with this one and will end up buying it again with each of our kids as they get to the age of needing a graphing calculators. This is the top of the line, highest calculator allowed on the ACT.

This is a very capable graphing calculator from the company that put scientific calculators on the map. This particular model was recommended by my daughter's college calculus professor, so I ordered it without hesitation. Feedback from hands-on use confirms the display is great (bright), and the 3D graphing is also quite nice. Charge time is also good, with lack of disposable batteries being a bonus.

Great Calculator! The calculator came right on time for school, in a neatly packaged box, and the packaging and calculator looks brand new, and untouched. Although this is a fairly pricy calculator, it was worth it for the functions and amazingly high definition color screen!

I bought this to replace my TI-83 Plus. So far I am really happy with it. There is a bit of a learning curve at first when trying to find out where everything is. I do like the color screen and I like the lithium rechargeable battery. The battery last a very long time on a charge and it can be replaced by unscrewing the one screw to the battery door. The only annoying thing so far is the screen has a slight flicker when it's at the lowest screen brightness.

The package includes the calculator, a calculator cover, a USB to mini USB cable, a USB to wall adapter, a mini USB to mini USB cable (for syncing calculator to calculator), a CD with a manual on it and a card with a product code for the TI software. I attached a photo of all the contents and the box it came in.

I would highly recommend this as a TI-83 replacement.

They didn't have the item at our local store, but it was shipped and received in 2 days, at no extra charge. My son is happy to have this calculator.

I purchased this TI-Nspire CX calculator for my son who is taking Calculus. Initially I was concerned, because there is a learning curve associated with this particular TI model, in that it is performs differently than the model that most of the students in the class had. On a couple of occasions I almost caved and bought the other version. It has now been about a month and my son is happy with the functionality. Now that he is getting the hang of the short cuts, he will be trying out the software that accompanies this model. I'm hopeful that he may be able to store his work directly to his laptop. - My rationale for purchasing this model, was if he continues with math or science at the college level, he might need some of this additional functionality.
