Casiofx-9750GII, Graphing Calculator, Pink (FX9750GII-PK)

Bought for my daughter to Sixth Form studies, it works fine.

The newer fx9750GIII comes with a natural display as standard, Python programming capability (to a limited extent), and the ability to take add-on apps. It also features an exam mode suitable for IB use (no need to delete apps and programmes for the exam), twice the internal memory, syncs directly with a PC without device management software, e.g. FA124, extra regression modes, and a 3-segment battery monitor.To most owners, however, half the internal memory won't be a problem, and FA124 device management software is free of charge and works well. The ability to add apps (including Python - see photo), exam mode, a battery monitor, and a natural display, can all be achieved by uprating the operating system software to the fx9860GII.The newer model is less robust, and nowhere near as attractive to look at as this one, so this older version is well worth buying if the price is right.Uprating it to the fx9860GII o.s. (easily done - plenty of tutorials) then puts it almost on par with the newer model.Ten years on, and the fx9750GII remains one of the easiest to use graphical calculators on the market, catering for both college and university students alike . It ticks just about every box for A-Level and I.B. use. Though it lacks a natural display capable of giving exact answers in terms of fractions, surds or pi, this can be remedied by upgrading the operating system to that of the fx9860GII. It then also offers vector commands, spreadsheet capability (S-SHT), document capability (eACT) and the capability to add apps by Casio such as Geometry and Physium; or third-party apps such as Algebra and CAS (see photo).These last two apps provide useful c.a.s. features, such as the giving the full derivative of a function in terms of x, not just the numerical value, and the ability to expand algebraic bracketed expressions, even those raised to a positive integer power and (with Algebra - see photos) containing complex numbers.Algebra (see photos) also handles simple, indefinite integration, when the integral is in standard form or soluble 'by parts'. It will also give the quotient in polynomial division, and simplify some trig expressions by using the correct trig Identity. CAS will express an integer as the product of its prime factors (useful for GCSE).For differentiation, both allow second or higher derivatives to be obtained quickly, either by repeated use of the command, in the case of CAS, (diff(diff(.......)) or, in the case of Algebra, diff(ANS), when the calculator displays the first (or higher) derivative.Neither app will be as good as a proper c.a.s. calculator like the TI NSpire CX CAS, but as free add-ons, they expand the capabilities considerably, and are well worth having. Calculators with c.a.s. facilities are mostly banned for use in exams, so to many students, what they offer is irrelevant.With a host of just about every statistical function you could want, including Chi-Squared GOF, t-tests, f-tests and ANOVA, many students don't even scratch the surface of its capabilities. Being fully programmable as well, using a version of BASIC, you can write your own software (see photo) to cover anything within reason you'd like to have included, but not built in to the operating system.Battery life is amazing, and it's also very robust, with a nicely recessed LCD panel, well designed keypad, and protective sliding cover.Pink is fashionable these days, but many dislike it as a colour. In my opinion, the fx9860GII looks hideously ugly in it, but for some strange reason, this one looks really good; the alternative colour schemes appearing dull by comparison! Without sounding sexist, it's bound to have added appeal to female students!Programming in BASIC allow you to write advanced software, thanks to the huge range of subroutines , covering virtually every function the calculator offers, and extensive range of mathematical symbols together with loops, IF statements, GOTO jump commands, logic statements and formatting options.The newer model looks less attractive, especially the replay toggle button. It's plastic painted to look like metal (not so on older models like this one) and its cover is less scratch resistant. Also worth mentioning is that already, newer models such as the European equivalent of the fx9860GIII and fxcg50, are appearing on the market as 'for spares or repair' with stuck/damaged keys, whereas I've never noticed older versions advertised this way! The newer models may not withstand the same degree of abuse, and end up with a shorter life span.I'll close by saying that even GCSE students would benefit from some of the features this calculator offers, but more importantly It's fun and could provide hours of entertainment! Its appeal is far ranging; benefitting both school and university students alike.Upgrading the operating system to give a natural display, may be a chore to some, but adds extra appeal to those with a liking for I.T. and working with electronic equipment; or anyone liking d.i.y.Upgrading is carried out by running a software package on a Windows' p.c. , called fxRemote, with the calculator connected by USB lead, after having got it to display the "OS ERROR Please update OS" BIOS screen. This is achieved by pressing the keys: F2, 4, A/C, and the reset button at the back, simultaneously; then releasing them after a few seconds, and transferring your fingers to the keys: 9 and X, and toggling them not too quickly.This software package, and ROM images of the latest fx9860GII operating system (02-09-0201) are available on tiplanet, as free downloads. Upgrading the operating system is a quick and easy process, and there are many tutorials out there to talk you through it. Read my review for the standard fx9750GII in navy blue and white, for more details. Do beware, however, that upgrading carries the risk of severely damaging the calculator, if you use the wrong ROM file, and it also invalidates the Casio 3-year warranty. That said, the warranty is only valid when buying new, from recognized suppliers, and if you follow my instructions to the letter, the risk of damage will be negligible! As for reliability, there are plenty of these models now over 10 years old and still good as new. Some of Casio's older calculators are still functioning even after 40 years!In summary, the fx-9750GII remains an incredibly useful and versatile tool, catering for all needs. Robust, aesthetically pleasing, easy to use, with excellent battery life and capable of being modified to take a large range of useful add-on apps and programmes (mostly free) the name "Casio" belies its usefulness. "System Casio" would seem more appropriate! This is the tool that should be in every classroom, if we want a greater uptake of students for maths and science degrees; or anyone doing a course with advanced mathematical content.BASIC is a good way to learn the rudiments of programming, and this calculator makes learning it fun, thereby providing an excellent way of improve one's programming skills, without the need for Raspberry Pi (or something similar) in the classroom! More to the point, if you want an 'A' at A-Level Maths, one of these will give you the best possible chance of achieving it. If permitted, it'll also be an invaluable aid at uni : a pretty good deal for your money in my opinion!

Just what my grandson asked for. I didn't like the packaging... It was stamped all over saying "school property", but I guess It is an appropriate calculator for his needs.

Good calculator, wish they sold it in India so the warranty wouldn't be void.

Works perfect for Trig through Calc. Takes a bit of extra work as most teachers only show how to use the Ti-84 but i enjoy learning it and it definitely is worth saving the money.

I bought this for my son who has been addicted to his iPad but also loves math. I saw a Reddit that suggested that sophisticated calculators might be interesting enough to hold the attention of a child the way an iPad might but also be more specifically educational and less psychologically toxic (especially no ads). It works great, he loves it! Thanks to the seller for providing this great product.

Good calculator. It wasn’t exactly the right calculator for college statistics, but with some online research we were able to make it work. And it saved us a ton of money, so I’d say that it was worth it.
