New Casio FX-85GTCW Black Scientific Calculator

Product Information

CALCULATION: arithmetic, trigonometry, logarithms, exponential, hyperbolic, equivalent ratio, number line fx-85GTX contains additional features such as clearer display, clearer menus, faster processor and 14 additional functions. Allowed in every UK exam where a calculator can be used. Recommended and approved for Key Stages 3 & 4 (including GCSE, National and Higher, Junior and Leaving). The large Natural Textbook Display (Natural-V.P.A.M.) shows mathematical expressions like roots and fractions as they appear in your textbooks which increases comprehension because results are easier to understand. Our entry-level scientific calculator with solar power. The functions are arithmetic and scientific calculations, statistical calculations including quartiles, table of values for up to two functions, and calculation of equivalent ratios. There is a Maths Box with probability simulation, number line and unit circle display.

Sept 2023: A fellow Maths tutor on Facebook recently had a meeting with a Casio representative to discuss these new models. We are told that the intention was to make them more like a phone to use (though I find it hard to see much resemblance myself) and that younger children who aren’t already accustomed to a particular scientific calculator layout have adapted well to its use. However, we are talking about 11-year-olds, and I find it hard to imagine that they’ve been using many of the functions needed for Higher GCSE and A-level Maths! Another one that’s been brought to my attention: the functionality of the button has been changed so that it no longer “attaches” itself to the preceding number. It’s not actually wrong but it’s a change that will be very confusing for many students! Remember I mentioned that a graphical calculator is much more complex to operate than a scientific one? The CW models have narrowed that gap considerably – and not in a good way! In short, the new CW calculators are a lot more complicated to use than the older X models, and don’t offer any significant improvements that I can see.

That’s EIGHT key presses instead of two – not to mention having to remember which menus to go into.

There’s no S-D button for simple conversion of results between fractions and decimals. The answer always defaults to a fraction, and to get it into decimal format you have to either (a) press FORMAT, use the arrow keys to select the preferred format and press OK or EXE, or (b) press Shift then EXE to get a decimal approximation (i.e. rounded decimal form) – but the latter option will only work correctly if pressing EXE doesn’t prompt the calculator to carry out another calculation.When the new specifications came in, Casio brought out new upgraded calculators called the Classwiz series. The GCSE model was the Classwiz fx 83/85GT X, and included a few extra features that the GT Plus didn’t have, although the GT Plus was (and is) still perfectly adequate for GCSE. Our entry-level scientific calculator with solar power has been upgraded to the latest ClassWiz technology. The Casio fx-991EX is Casio’s most advanced scientific calculator, providing 552 functions and is suitable for Key Stages 3,4 and 5, to include A /AS level.
