Very impressed by quick home delivery!

I lost my calculator and needed a new one for a school exam the next day. Ordered this at 5pm and the calculator had been delivered to my door by 7pm the same evening! Really quick and efficient, very pleased. The calculator is great and works well.

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.

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.
