Casio FX991ES Plus Dual Powered Scientific Calculator. 4.9 5 8 10
Excellent calculator Has the features needed for higher level maths studies.I have found no problems with it and it has made things much easier in my studies. 20 January 2015
Very good This calculator is slightly better than the older one I had. It is much more practical and I don't have to do some extra calculations to get things right because it take almost all the formulas I need. 31 December 2014
The product is easier to use It is better and more powerful than my previous scientific calculator. More features and easier to use. 20 November 2014
Very helpful! Should have bought one before! I recently sat my GCSE maths exam, and I used another scientific calculator. I subsequently bought the Casio FX991ES and I should have bought one earlier. It is user friendly, fun to use and helps you understand calculations. This calculator is not necessarily an easy option for answering maths questions. The calculator helps you to apply what you know. Excellent for calculating fractions, and gives you the option of an answer in fraction or decimal form. Very useful indeed. 08 July 2014
Calculator for A levels Comes with an operating book which is written in very tiny fairy writing. If I were designing a calculator with multiple operations I would make the print much larger on the actual calculator. To use at a desk where you are going to relax to use it. If you are doing everyday basic sums, on the move then yes tiny is useful to slip in your pockets. I am doing a self study as a mature student out of curiosity. 15 April 2014

Since you have confirmed that this calculator cannot do recurring decimals, why are you continuing to advertise this calculator as being able to do "recurring decimals, Prime Factorisation and Verify"

For this calculator to have these abilities, it would have to be the "FX991ES Plus C" not "FX991ES Plus. If it does have these abilities, then you are displaying the wrong image for this calculator because :- the "VERIFY" function should be above digit "6" : - the "recurring digits" function should be in red above the square root key : - and prime factorisation key "FACT" should be written above the "degrees minutes seconds "key.
