She's studying computer science and she says this is the best tool she has had to solve her math problems. Great power efficiency, the batteries last a long time in a daily basis use. Overall it is a great instrument, an useful tool for engineering students. At first hand it seems quite complicated to handle, but first impression doesn't last much. It has nice graphics and neat programs, with a large variety of programs and methods, and you can even program them yourself with basic programming skills. Pros: It is somewhat complete, has nice graphics tools and capabilities, the battery last long, it is programmable and has great alternatives for math writings forms. It has all basics and a large variety of methods, and you can find on internet a lot of programs for physics, economics, electrical solving, probabilistic and others Cons: It doesn't have much memory so you can't have many methods programs at once at the same time, meaning if you want to have the electrical circuits solver program and a Lagrange or New-Raph solver, or Gauss or Thevening among others, you have to choose one at the time because it won't be able to storage them all. And there are a few methods missing like Laplace transform, Inverse Laplace, Integral Asymptotics, Chrombach alpha and other advance methods in math, calculus and probabilistic. But the price is excellent Review: Great Product! Very easy to use. Awesome Functionality. - Great Product! Very easy to use. Awesome Functionality. This is one of the best education investments that i have ever made. Very happy with the purchase. The Calculator is simply great. I understand that in North America teachers and books only uses TI Calculators because is the tool that they have been using for years. Otherwise here in South America most of the High Schools/Universities uses Casio. I use to work with a Casio Graphing FX-7400 for 7 years and was really happy with it. Like my old Casio this new also do the graphing but it does twice as fast!. The FX-9860 Gii is a beast!!. Super fast calculations. The fact that comes with screen light are really nice!. Love the fact that come with 4 size AAA batteries so there is no need to recharge every week like TI or HP color screen calculators. I highly recommend it. Great Price Great Value. Thank you to Casio for the great work building this beast!. ## Features - REF/RREF function, random integers, unit conversion, new types of regressions, chi-squared GOF function, 9 new probability functions, pie charts & bar graphs, graph X=f(Y) and much more - 1500 KB Flash ROM - Built-in eActivity and spreadsheet applications - Icon-based menu adds to overall intuitive usability - Direct connection to Casio projectors - Data transfer from unit-to-unit and from unit-to-computer - New LCD backlight for superior visibility - New manager software available ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #225,908 in Office Products ( See Top 100 in Office Products ) #85 in Graphing Office Calculators | | Customer Reviews | 4.7 out of 5 stars 1,292 Reviews | ## Images ![fx-9860GII Graphing Calculator, Black - Image 1](https://m.media-amazon.com/images/I/71Jk9W1ODBL.jpg) ## Questions & Answers **Q: Does this calculator have built-in computer algebra system?** A: No, this is definitely not a CAS (Computer Algebra System) calculator. **Q: Does this calculator come with a protective case and USB cable?** A: a fairly rugid case and both USB and sound cable **Q: is it programmable?** A: This calculator does give users the ability to program simple mathematical things.

Thank you to Casio for the great work building this beast!. ### ⭐⭐⭐⭐⭐ superior to the TI series in terms of crisp LCD + backlight *by H***I on December 6, 2010* Since my high school and college days, I have been fond on the Texas Instrument series graphing calculators (TI-82 and TI-83) for home use. However, I have had the persistent problem that I cannot see the display in dim lighting, and dust accumulates behind the protective plastic screen (at least on both of my TI-82s). There's no point to have a graphing calculator if you can't read the display without squinting. In contrast, I have found this Casio graphing calculator to be superior in terms of its display, specifically the crispness of the LCD and the backlight feature. You can also customize the power-off and backlight timing, which is convenient. In fact this calculator is the only multi-line calculator on the market that I could find with a backlight (though there are some guides on blogs and personal webpages on how to through the trouble of custom modifying a TI series calculator to incorporate a backlight). One minor complaint is that the buttons on this calculator are slightly smaller than surrounding plastic case, so they jiggle around slightly in a cheap, toy-like fashion. ## Frequently Bought Together - Casio fx-9860GII Graphing Calculator, Black - WYNGS Protective Case for TI 84 Plus/TI 83 Plus/Casio FX-9860GII / Casio FX-9750 GIII/Casio PRIZM FX-CG 50 Graphing Calculator in 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.tw/products/1151130-fx-9860gii-graphing-calculator-black](https://www.desertcart.tw/products/1151130-fx-9860gii-graphing-calculator-black) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-07-10*
