Texas Instruments really hit it out of the ball park with this calculator. This is the most beautiful and user friendly graphing calculator I have ever seen. Keep in mind I have not owned a graphing calculator since I had an old TI-81 in high school 15 years ago. I am currently going back to school studying electrical engineering and this calculator has already been a lifesaver in the two weeks I've owned it. So far, I've mainly used the Computer Algebra System features of this calculator. The fact that I can use this to solve complicated integrals, a system of equations or do a partial fraction decomposition is a huge time saver. I've already proven time and again that I can solve these tedious, time consuming problems by hand and isn't this the entire reason man invented calculators. It means more time that I can use to better grasp the advanced math and physics concepts I'm being taught. That's a lot considering I work 30 hours a week on top of a full time school schedule. To me, the best part of all is the user interface. The "pretty print" allows you to enter a problem exactly how it appears on your page. You can leave your equations in mixed fraction form and don't have to take any extra time to convert them into a matrix as you would need to on some of the other TI models. Also, the menus are laid out in a format that's similar to a personal computer. This greatly reduces the learning curve associated with using a brand new graphing calculator. I do also love the built in rechargable battery. I charged the calculator when I recieved it and I'm still at about 50% power. The claim that a typical charge lasts for two weeks of normal usage is definitely true. I've read some review that worry about running out of power at an inconvenient time, but I think as long as you remember to charge it at some point within a week before a test you will be perfectly fine. While I haven't used the graphing features a lot, the color screen does seem to be a huge advantage when plotting multiple functions. This calculator also has a lot of other features that I'm sure are fantastic, but I can't really review because I just haven't had the time to explore them in depth. My only small complaints have to do with screen glare and documentation from TI. While the color screen is beautiful, there is a terrible glare if you try to use this outside in the sunlight. But, this is not a huge deal since I use this for student purposes and I'm not ever outdoors when I'm doing my homework. There is also an extreme lack of in depth instructional information on Texas Instruments website. I'm sure this is because there are just way too many features to give a comprehensive in depth coverage of everything. Luckily a quick google search has given me answers to any operating questions I've had so this has also (so far) not been a problem. Overall I would reccomend this product to any college student taking advanced math and science classes. You relly cannot go wrong. While you may be able to get apps that can do the same things on a tablet or computer, you generally cannot use those devices on tests. Every one of my classmates who has seen me use this cannot beleive how awesome it is. In fact, I think Texas Instruments owes me some money for all the advertising I've given them. Review: Want color in your Graphing Calculator? - This is one of the first graphing calculators, just behind Casio, that provides a color display. So what is great about this calculator? 1. Templates, templates, templates! Have a hard time understanding how to solve an integral or a system of equations on your TI-89? The TI-Nspire Cx CAS has easy to understand templates for solving integrals. In other words, this calculator will set up an integral just the way you would see it in your book, simply tab or arrow over to an empty box and fill it in. 2. CAS (computer algebra system) This helps solve for variables and can help simplify expressions that the non-CAS calculators couldn't hope to do. For just 10 or 20 dollars more for this feature (it is included in this calculator!), it adds a whole new level of functionality to your calculator, and the non-CAS calculators will tease you about these functions, but will tell you that CAS is needed in order to perform them. Also, This calculator looks more professional than the standard CX calculator, at least in my mind. So what is good about this calculator? 1. The screen provides a clear display, of course, the display could be improved on, but it really doesn't seem that necessary. Another difference is that the screen is in line with the rest of the calculator (the screen is not indented into the calculator as it is with most other models), providing little protection against accidental drops. 2. The sleek design. It looks much more professional than the older Nspire models and is much more sleek, but it provides a little worry when it comes to strength and durability, but you would have to be rather careless in order to break it. So what is slightly annoying about this calculator? 1. The Li-Ion battery. This may be a difference in personal opinion, but I don't think I should have to charge my calculator at least every two weeks and eventually every other day or so. This calculator runs off a standard cell phone battery and so the longer this calculator is used, the faster it will die, and I just prefer that my calculator runs off batteries and works for months at a time. (Hey, uh, maam, I know we're taking a test and all, but, uh, could you move over a bit so I can charge my calculator?) That really shouldn't be much of a problem because it does have a battery bar, but if you forget one day, and happen to have the recharger, it just seems strange compared to keeping a pack of batteries as a spare. -Battery correction located towards bottom of review Added Friday, August 26, 2011 This calculator attempts to emulate or copy the general format of a laptop computer that happens to mostly only function mathematically and scientifically in the sense that it is possible to buy a variety of different sensors for this calculator. I also forgot to mention that this calculator has what is similar to a touchpad that seems a little bit, well, touchy (The scrolling icon doesn't show up unless the calculator detects/thinks you are trying to use the arrow pad as a touchpad). After I have had a small amount of time to try this calculator, I have found that it seems to be the type of calculator that is used more often for homework, not tests, because it is a great tool when you are not under pressure. This may be for a variety of reasons, one of which would be that I am much more familiar with the general layout of the TI-89 and TI-83/84. Before considering purchasing this calculator, one who has not owned a previous version of the Nspire line, should determine whether he/she is willing to put the time in to understand where to find the functions he/she will want to use. In addition, the calculator features a basic keypad containing the alphabet in the abc, rather than qwerty, format which some may find annoying. But! Remember that if Texas Instruments were to make a qwerty keyboard on their calculators, then these calculators would not be allowed during most tests due to standard regulations. In conclusion, I believe that you should probably only spend your money on this calculator if: 1. You previously owned an Nspire model, AND enjoyed using it! 2. You have never owned a graphing calculator and want the best of the best. (You know, color, resolution, processor, touch pad, three dimensional graphing, templates, sleek design, semi-intuitive button layout etc etc.) 3. You collect TI brand calculators 4. You enjoy manipulating graphs, rather than simply calculating functions. I'm sure there are quite a few things I may have missed, but I wanted to be sure that I addressed a few more of the aspects of this calculator and to come up with a guide to whether this calculator may be right for you. Regardless of my main points, and despite the comments and reviews about cracked screens and assaults on durability, this calculator works and is relatively durable. If you are the type of person who drops your phone every three seconds and who works with dangerous chemicals without washing your hands, then this calculator, and any calculator over $20, may not be right for you. But if you are the type of person who is going to set the calculator on a table or desk and use it for what it is meant for (hint: calculating, NOT playing catch with or determining the gravitational constant by dropping it) then you will more than likely not experience any durability issues. Added Sunday, August 28, 2011 *Battery Correction* I have recieved note that the Li-Ion battery, in fact, should run just as long as a set of AAA batteries. While this is true, the Nspire calculator has many power-saving options that can significantly increase battery life at the cost of power up time. When this calculator is "shut off" its true default is to stay in somewhat of a very low power sleep mode that helps lower boot times. This sleep mode can be lengthened or shortened depending on your use, but the difference in boot time changes by roughly 10 seconds. (The calculator starts at about the same speed of the 89 titanium when coming out of sleep mode, but when it is completely turned off, then the calculator displays a load bar for about 10 measly seconds). The difference is that when you shut off a Ti-89, at least to my knowledge, the calculator completely shuts down and does not use any battery power. This allows for extended use for up to months as I have accomplished beforehand. But! I reviewed this calculator on either the first or the second day after I bought it, and have not needed to recharge it yet. (It has been nearly a month) My actual rating for this calculator would be about 4.5 stars. ## Features - Ideal for Pre-Algebra, Algebra 1 & 2, Trigonometry, Geometry, Pre-calculus, Statistics, Business & Finance, Biology, Physics, Chemistry, Calculus, AP Statistics, AP Physics, AP Calculus, and Linear Algebra. - Full-color screen with backlit display. - All the functionality of the TI-Nspire CX handheld plus a built-in Computer Algebra System (CAS) - Eleven interactive zoom features ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004NBZAYS | | Best Sellers Rank | #294,977 in Office Products ( See Top 100 in Office Products ) #102 in Graphing Office Calculators | | Brand | Texas Instruments | | Calculator Type | Business, Graphing | | Color | Black | | Compatible Devices | Laptop | | Customer Reviews | 4.7 out of 5 stars 3,877 Reviews | | Display Type | LED | | Enclosure Material | Plastic | | Global Trade Identification Number | 00033317203963 | | Item Dimensions L x W | 7.28"L x 3.15"W | | Manufacturer | Texas Instruments | | Mfr Part Number | N3CAS/GC/2L1 | | Model Name | Nspire CX CAS | | Model Number | N3CAS/CLM/2L1 | | Number of Batteries | 1 Lithium Metal batteries required.

The calculator does come sealed in the original packaging just as if you purchased it in the store. Also includes wall charger/USB upload cable. **Q: Is there anything this calculator can't do that the TI-Nspire CX can do, or are they the same, just with cas?** A: The allowed calculators list for testing are updated periodically. The following is where you can check allowed calculators. I use my TI-Nspire in class and on tests at school. In fact, my calculus teacher went and picked on up after seeing mine and another student's. https://sat.collegeboard.org/register/calculator-policy **Q: As a highschool student in Algebra II this year, is it worth buying this or just buying a version of the TI-84 (either silver or silver + c)?** A: I'd get the Nspire CX CAS. It will do all the algebraic operations needed for Algebra II and college algebra. It will also do calculus operations and solve some differential equations. It works more like a computer than other TI calculators and will take more time to master. I have used the TI 83, 84, 85, 86, 89 Titanium, 92 and Nspire CX CAS. I currently use the 89 Titanium and the CX CAS. I find the 89 easier to use but the CX CAS is more versatile and more powerful. User's manuals, tutorials and videos are available on line.I'd find out what calculators are allowed in your classes before making a decision. **Q: Is this as easy to use as the TI-83/84. And is get the TI-84 better for High School?** A: This is a great calculator and it is pretty easy to learn to use. I have a TI-83+, TI-89, and TI Nspire CX CAS. I like the 89 and the CAS. There are 2 Nspire models that look alike: the CS and the CAS. If you can afford the price difference, get the CAS. It can solve complex problems and provide a "pretty-print" answer. In either case the Nspire is better for students, although the 89 is geared a just bit more toward engineering applications. The 84 is able to do quite a bit, more than enough to get you through high school and college, but the other models I have talked about are far superior in every possible way. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best investment I've made as an engineering student! *by R***. on October 7, 2011* All I have to say is WOW!

I originally got the TI-Nspire CX, but within about 5 minutes I knew I wanted the CAS feature. The return process with Amazon was awesome and I was very happy with the CAS version. I had debated prior to ordering, but not knowing much about math, I wasn't sure if it would be worth it. Now having just completed the semester, it is completely worth it and then some- here is why: 1) some problems you have to work in college algebra will have two or more answers. Without the CAS version, only one answer is displayed and there is no indication that other answers exist. With the CAS version, the applicable answers are displayed. 2) With CAS, the calculator can do more difficult math calculations. If you're a math wiz anyway, this probably isn't that big of a deal. Personally, I loathe math, put it off for as long as possible, literally the last class I needed for my degree. Getting this calculator was a game changer, I just wanted to get through the course. Sure, I learned along the way but if the calculator can do the heavy lifting, then I feel it should. Once I learned how to use this calculator, it was a matter of entering the equations into the calculator, pressing enter, and writing down the answer. Quadratic equations became almost as easy as figuring 2+2. As a side note, I just looked on the SAT approved calculator list and this is currently on it, so I don't know why anyone would buy a different graphing calculator unless this advanced level of a calculator isn't allowed in your test. With each week's homework assignment I found more the calculator can do- there are tons of demo videos on youtube that were helpful. Then the day before my final, I stumbled on to what may be the coolest feature of the calculator which is the way programs can be written. You don't have to be a programmer, just download some of these to the calculator, it is very easy using the supplied software. I downloaded programs to find the slope and solve quadratic equations and suddenly I didn't have to memorize equations any more. The great thing is you can use it for these sort of things as little or as much as you want- personally I opt for having the calculator do as much math as possible. The student software that comes with it is very handy if you have dual monitors, basically it is a calculator emulator and does everything the calculator does on your computer. I could enter things in much more easily with my computer keyboard than the tiny keys on the calculator so I used the software for homework and the calculator for my tests. Finally, I would say the proof that this calculator is worth the cost is to imagine how much I disliked algebra before this semester in comparison to my final grade for college algebra from my university which was just over a 99%. ## Frequently Bought Together - Texas Instruments Nspire CX CAS Graphing Calculator - Elonbo Carrying Case for Texas Instruments TI-Nspire CX II CAS/CX II/CX/CX CAS Color Graphing Calculator, Extra Zipped Pocket Fits Charging Cable, Charger, Manual, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/792279177-nspire-cx-cas-graphing-calculator](https://www.desertcart.vn/products/792279177-nspire-cx-cas-graphing-calculator) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-10-27*
