Is this a "TI Nspire CAS" or a "TI Nspire CAS+" calculator?

It is just CAS, no +. But it is pretty powerful for a high school even graduate college student. The thing is it takes time to master using it.

This calculator is a TI Nspire CAS clickpad, not is TI Nspire CAS+, good day

I believe it is a separate purchase. I was pretty satisfied with it, although I personally think I could have designed it better. I propped it up additionally to optimum configuration, but overall it worked well. I had my calculus book (hardback) on the left; I'd work problems on paper on the right; Upper left was the full-size paperback solutions manual; Upper shelf right I had the TI-84 plus manual and/or the calculator itself. Talk about a workstation.

No, you can not use the CAS version of any calculator on the SAT or ACT. You can, however, use the non-cas version of this calculator, and if this is for education, then that is the calculator to purchase, not this one.

I ordered it for my CX (not CAS) and it fits and works properly. I think it won't work on older models (it's easy to recognize cause older models look a lot wider) . If your calculator looks like the picture above should work.

The "del" key is the delete key, which is essentially the backspace you are looking for. I highly recommend this calculator for the features and price. TI-84 will get your son through high school and also help in college. In college you will most likely be needing something like a ti-89 though (also has a del/backspace key). :)

Haven't used the HP. The Nspire cx CAS is very nice. I have no complaints. The user interface is simple enough to use for quick computation and capable enough to do a lot more. I have the TI Software but haven't tried to write my own programs yet, but this software will make it quite nice should I need to. I'm guessing you'll be working with complex numbers, matrices, linear algebra stuff and the Nspire is a champ for all of those and more. By the way, make sure you get the CAS version.

From a purely technical standpoint, the prices should be reversed (and both prices halved or quartered). I think the Casio is superior in many ways. However, as some commenters have noted, you have to be careful if a class requires a particular make/model calculator, and some textbooks have key-by-key walkthroughs that are TI-oriented for completely commercial (not quality or educational) reasons.

It work excellent, it makes any calculus you need, include programming in TI-Basic that it´s very usefull. I´m very happy with my TI Nspire Used buy in Amazon for less $30.

For my part, the TI nspire CX CAS is the tops for any and all advanced math problem solving. You have the ability to "program" it to do almost any math problem imaginable if that solution is not already in a downloadable pack. There are a lot of good tutorials and examples as well as math packs that can be loaded. The ability to connect it to your computer and generate your math solutions and then download it to the device is great. Hope this helps.

Play the YouTube video, TI-Nspire CX CAS Algebra overview. The main difference is how it handles Basic Algebra. This video points out these differences. http://youtu.be/vxooBetzvvc. This is the guide, Ti-NspireTM Guide Algebra Fundamentals: TI-Nspire and TI-Nspire CAS Revealed and Extended (TI-Nspire Innovation in Education Series Book 1) used in the YouTube video.

the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup. The newer model though only sports that one lithium. If the one you have or intend to have still uses the legacy battery system for this entire TI programmable line you should use AAA lithium's rather than alkaline. don't use ni-cad or ni-mh. finally, the single lithium rechargeable lasts a long time... AND the calculator even sports a battery monitor. Personally THIS is the battery system I'd be looking for and not the legacy type.

Yes, only this version allowed. Do not get the TI-Nspire CX CAS version. The CAS version is not allowed.

Yes, this calculator has a Computer Algebra System that is very sophisticated. The list of built in functions can be obtained by downloading the Operator Manual from the Casio website.

Don't know what you mean by 'function limits'. Casio CG10 is best if you've been using the CG83 or 991 before as it works in the same way. The Nspire CX is probably better but is much harder to get started with.

Yes, mine was! Also the extra free module to turn it into a TI-64 calc is a great deal!

CAS calculators in general are often not allowed to be used on assessments in algebra 2. I know in NY state you cannot use this calculator on the state exam at the end of the year. That being said, there are TI-Nspire graphing calculators that are not CAS, and allowed on most exams when in test mode.

No, this one links from one calculator to another. The one that connects to the computer (through USB) looks like this. http://www.amazon.com/Texas-Instruments-94327-Graphlink-USB/dp/B00006BXBS/ref=sr_1_1?ie=UTF8&qid=1393361764&sr=8-1&keywords=ti+83+usb+connectivity
