Classy Casio

As a maths teacher/ tutor i need a reliable up-to-date calculator. This model is only one or two recommended for next years A-Level (change of specification) - Appears well made, looks expensive, with a much improved display. Loads of functions (some new). Ebay purchase (Far east) made it quite low priced compared with UK supplied - but identical calculator, in sealed box and UK instructions. Great.Read full review...

Revamped fx-991ES Plus

Just on looks alone, most would give it 10 out of 10. With its high contrast screen and attractive icons, it makes all other calculators, anywhere near this price, come across as outdated. Improving on the features of their already fantastic value-for-money calculator, the fx-991ES Plus, it now offers everything the A-Level or IB student could hope for from a non-graphical calculator, and is the number 1 choice in schools, by many maths teachers. Despite using symbolic logic to write inequality regions as solutions to polynomial inequalities in x (a featured not introduced by Casio before) , JCQ have approved its use in GCE exams - wires were obviously pulled at the highest level.

BEWARE OF THE CHINESE COPY. IT LOOKS IDENTICAL BUT ONLY HAS 240 FUNCTIONS. THERE ARE TRADERS ADVERTISING IT, SAYING THAT ITS GOT 552 FUNCTIONS, WHICH IS AN ABSOLUTE CON!

Excellent Choice!

I was looking for a calculator for my son with advanced features and spotted the Degree/PHD bit. Well worth the extra money and my son is over the moon with it. The description was very detailed even although I didn't understand it so the fact that it mentioned Degree/PHD I knew it was a good choice. I would highly recommend this and its 4 times more powerful than its previous model.Read full review...

Excellent Calculator

Bought this calculator for the Engineering functions, specifically for working with complex numbers.
The time saved, by being able to swap between polar and complex co-ordinates is massive.
I have also started to use the spreadsheet function for recurring equations, excellent.
Worth while taking the time to download the instruction manual in full size, and review all the calculator features.

Love it!

I won’t lie, I was a bit hesitant when I first saw the packaging that it came it. However as I opened the box I was pleased to see it in great condition. So far works to perfection and is hopefully going to be a major key to my A-Level Mathematics success!Read full review...

Great value but lacks a graphing feature.

Much cheaper than the CG50 and does everything you need for A-Level and beyond. Does not have a graphing feature, so if you are not a confident graph sketcher, this may not be the right calculator for you in an exam situation.Read full review...

I really should stop buying calculators

I love calculators and sliderules. This model, the CLASSWIZ, has been out for a couple of years and it is excellent. Easy to use with a whole host of functions. Casio withone or two other models seem to have got away from the standard GCSE calculators with this impressive good-value machine.Read full review...
