CASIO Graphics Calculator FX-9750GII

Product Information

The Casio fx-9750GII is powered the old fashioned way, 4 AAA batteries. If you buy the calculator new, it will come with batteries. You make your selections using one of the 6 corresponding “F” keys. Doing all of this menu navigation on such a small percentage of the screen is tedious. You can only see 6 command options at a time (5 if the option to scroll is taking up one of those slots). And each selection can only be 3-4 characters wide so there are lots of abbreviations that are hard to understand. The Casio fx-9750GII has virtually no competition in its price range. For an extremely low price you’ll get a calculator with almost as many features as the ever popular TI-84 Plus. Even though this calculator has a very low price, you shouldn’t overlook it as incapable. I was very surprised by the low price, and I wouldn’t have batted an eye if this calculator was on sale for a price closer to 2x as high as it is. The most obvious difference between these two calculators is their screens. The Casio fx-9860GII has a 2.97 inch screen (diagonal) and the Casio fx-9750GII has a 2.56 inch screen. This may seem like a small difference, you can see the difference in the image below.

The system is definitely still usable, I’m just a little disappointed that Casio didn’t think this aspect through a little better. I’d rather see a way to enter a menu that took up the whole screen without abbreviations.

The Casio fx-9750GII still does not have the capability to display some expressions as they would appear in a textbook. It still uses the old method of display, using things like small "L"s for fractions and carrots for exponents. The Casio fx-9860GII however can print answers and take input in the way you would see them written out. Below is the same expression written on the Casio fx-9860GII and on the Casio fx-9750GII.

The following list includes the features that the Casio fx-9860GII has and the Casio fx-9750GII does not. Anything not on this list is the same for both calculators. Programming is dead easy (the language is similar to BASIC) and with every text character and mathematical symbol available, together with the full range of programming commands you'd expect, you can write your own software to cover almost anything not built in - incredible! The other useful apps include: lists, matrices, dynamic functions, an app for graphing conics, recursion, financial functions, and an app for simultaneous equations and polynomials. If that's not enough, you upgraded the operating system to give it a natural display, spreadsheet, document facility and the ability to take powerful add on apps (free of charge) which give it CAS facilities.

From any screen, you can press the [MENU] button and be taken the main menu where you can run any of the 14 main apps on the calculator. The calculator doesn’t have anything super special or out of the ordinary when it comes to apps. For example, there isn’t anything like an app for unit conversions, or a computer algebra system. Finally, there's the Geometry app which allows you to draft shapes and/or lines and do other things like attach measurements of angles or line segments. This would really only be useful for a geometry student who wanted to experiment with different 2D shapes.
