Having used both the TI-84 and the Casio FX line extensively I would definitely say it's worth it to save a couple bucks for books or dorm supplies and go with the Casio. It performs all the same functions for a much more budget friendly price. The menus seem a bit daunting if you haven't used a Casio before, but once you get used to them they are really fluid. Review: Reliable School Supply - This calculator is essential for exams and the graphing functions is reliable. I am fond of the table that displays the coordinates of the graph in addition to the large display. All features are functional and that protective cover is convenient for protecting the screen and the USB connection enables the user to display what was entered on the calculator and the quality was decent for the price ## Features - Chi-squared GOF function - New types of regressions - Random Integers - Unit Conversion - REF/RREF Function ## Images ![Casio fx-9750GII Graphing Calculator, Blue - Image 1](https://m.media-amazon.com/images/I/71G1fllTsjL.jpg) ![Casio fx-9750GII Graphing Calculator, Blue - Image 2](https://m.media-amazon.com/images/I/91U2LfFw3AL.jpg) ![Casio fx-9750GII Graphing Calculator, Blue - Image 3](https://m.media-amazon.com/images/I/91cNeyMKo4L.jpg) ![Casio fx-9750GII Graphing Calculator, Blue - Image 4](https://m.media-amazon.com/images/I/61ooPVstTFL.jpg) ![Casio fx-9750GII Graphing Calculator, Blue - Image 5](https://m.media-amazon.com/images/I/81EKhuBbagL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great calculator, less expensive than competitors *by Q***S on November 2, 2017* I bought this instead of a TI-84 for my computer science and statistics classes and am very pleased. Having used both the TI-84 and the Casio FX line extensively I would definitely say it's worth it to save a couple bucks for books or dorm supplies and go with the Casio. It performs all the same functions for a much more budget friendly price. The menus seem a bit daunting if you haven't used a Casio before, but once you get used to them they are really fluid. ### ⭐⭐⭐⭐⭐ Reliable School Supply *by L***M on November 11, 2016* This calculator is essential for exams and the graphing functions is reliable. I am fond of the table that displays the coordinates of the graph in addition to the large display. All features are functional and that protective cover is convenient for protecting the screen and the USB connection enables the user to display what was entered on the calculator and the quality was decent for the price ### ⭐⭐⭐⭐ Decent calculator for a good price *by G***G on July 14, 2018* Most of the criticism I see here boils down to one thing: it’s not a TI calculator. This particular model lacks natural/textbook entry, which may be an issue for some, but it has all the basics, and is faster than similar TI products. The screen resolution is fairly low, but it’s readable. It does the job, and the price is right. It took me about an evening to figure this thing out, but this is not my first calculator by a long shot. The good: - fast - covers the basics. - runs a long time on 4 AAA batteries. - the calculator feels sturdy. - fairly easy to learn (in my opinion) Not so good: - low resolution screen - no internal flash memory to back up to - it’s too easy to turn the calculator on, a recessed power switch would be nice. (The competition has the same problem) - no data transfer software for the Mac (the newer Casio Prizm models do not need any special software, you can drag and drop files) If the budget will stretch that far you may want to take a look at the Casio FX-CG50. It has a higher resolution color screen, supports textbook entry, has more memory, it’s even faster and it works with a Mac. TI can get away with charging higher prices because they spent real money on teacher resources and training, and getting their calculators included in classroom materials. That does not make a TI calculator a better product, but if I had to buy a calculator for a student I’d have to think about deviating from the “standard”. --- ## 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.com.om/products/24526863-casio-fx-9750gii-graphing-calculator-blue](https://www.desertcart.com.om/products/24526863-casio-fx-9750gii-graphing-calculator-blue) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-07-06*
