This was bought last minute as a Fast Track purchase before starting a course. Comes with its own cover and does everything I need it to do. Would recommend it.

Questions & answers

5 questions | 6 answersAsk a question
Can you confirm that this calculator does "Recurring decimals, prime factorisation and has verify function",

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.

Is the information given in the "Technology Product description / spec" for this calculator false?

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"

Can this be used in the Maths A level Edexcel 2016 exam?

2 Answers

I am doing the AS exam and all my research shows that this calculator is allowed.
It can carry out numerical differentiation and integration, which is allowed, but it does not perform symbolic differentiation and integration.

Hi Dave,

Yes, this should not be a problem, but this depends on the examiners rules.

Thanks for using Argos Q&A.
