Casio fx-85GTX Scientific Calculator, Black

Product Information

Natural Textbook Display (Natural-V.P.A.M), shows mathematical expressions as they appear in textbooks. 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! The A-level model now has the generic equation solver function in the same place as the quadratic and simultaneous equation solvers, rather than in an apparently random position above the CALC button.

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. For GCSE Maths, you will need a scientific calculator, but just about any model will do; see AQA’s guidance below for a list of the functions you need. The new A-level specification required the candidate to use a calculator featuring certain statistical functions that the GCSE model didn’t have, so the new standard model for A-level was the Classwiz fx-991EX. This also included some additional functions to help with solving equations, so it could be useful for GCSE too. It’s also worth considering an A-level model, especially if you’re doing the Higher Tier and there’s a possibility that you might continue to study Maths in some form beyond GCSE. Teachers can request a free licence for use in classrooms, remote and blended learning (available in the UK, Channel Islands, Isle of Man and Ireland).For more information on what calculators are permissible in exams, take a look at my Clueless about Calculators blog post. Finally, a colour warning Until the current GCSE and A-level specifications came in (2015 and 2017 respectively), the standard calculator in most English schools for both GCSE and A-level for a good few years had been the Casio fx-83GT Plus – or the fx-85GT Plus, which was exactly the same except that it had a solar panel as well as battery power. That’s EIGHT key presses instead of two – not to mention having to remember which menus to go into. If you have the older GT Plus then it will still do everything you need for GCSE, so don’t worry about that! From the comments I’ve seen on social media from other Maths teachers, I’m far from alone in having a strong preference for the older Classwiz fx-83/85GT X and 991EX models over these new CW calculators. Casio doesn’t appear to have done much field testing of the new models before launching them on the world!

A lot of schools/colleges haven’t caught up with the change yet and are still telling students to buy the X versions, so at least yours is on the ball!Some schools and colleges required, and some still require, their A-level students to buy more expensive graphical calculators – calculators that can plot graphs on their screens, such as the CG50 – since these are often perceived to give the student an advantage. This may well have been true in the past, but the exam boards have got wise and nowadays exam questions are carefully worded so that the possession of a graphical calculator doesn’t give the candidate a significant advantage. Nice large clear display, a sliding case that you can slide on and use the calculator, so doesn't get lost.

The A-level models have additional functions such as solving quadratics and simultaneous equations which can be useful at GCSE too, as well as Statistics functions that you don’t need until A-level. So if there’s any chance of you continuing with Maths beyond GCSE then it’s a worthwhile investment. (You’ll probably need it if you do Core Maths too, though it does depend on which board and which modules you study. It – or an equivalent – is certainly required for the Statistical Techniques option on the AQA spec.) Our nominated carrier is Parcel Force. Deliveries are made Monday – Friday between 9.00am – 6.00pm (excluding Bank Holidays). The display on the calculator allows for more readable sums, fractions for example allow you to actually see one number abover the other one instead of using some weird symbol like the calculators when I was at school. 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.

Reviews

Gain a better understanding of mathematical expressions on the display screen, for example; roots and fractions as they appear in your textbooks, this will increase your comprehension because the results are easier to understand and in plain sight. If you require any further information relating to the Delivery service used, please call us at +44 (0)20 8208 9567. The display is certainly not like the one I had in school as it shows the calculation on the top row with the answer on the bottom which is brilliant as any mistakes can be easily seen. This model has the benefit of a large display and, more importantly for me as I get older, a much better lit display that makes it easier on my eyes. The fx-85GTX takes the UK's Number One Scientific Calculator a step further, by offering Solar Power to ensure no loss of battery during those crucial exams.
