1. Core 1 no Calculator
are we not allowed to use calculator in mathematics C1 (Edexcel)?
because i am having a hard time with numbers like Square root of 800009

Yes, we aren't allowed to use calc.

And also there is no need for calc in a C1 exam.

Core 1 is the only non-calculator paper.

but i am solving questions from the book like square root of 800009
which is hard to solve without a calculator

AEA is also non-calc

Remember one tip, if you find a very difficult calculation in a C1 exam, then you are doing wrong or there is a very easy method for it which you aren't spotting.

In the book there are a few questions which can't be solved without calc, but you won't expect them in the exam.

Often when they ask for an exact answer you leave it that form

Write as a product of its cofactors and use the Quaternion Division Algorithm.

I know some question in the edexcel C1 book, which can't be worked out without a calculator.

They require taking a square root, which is improbable to be done without calc.

soving a question like
5n^2 + 3n - 4000
using the formula

Is this a question you have invented? I guess it is because you can't solve an expression.

Do you mean solve the equation 5n^2 + 3n -4000 =0

Try to work out the following question without calc.

It is from the edexcel C1 book.

The book gets the answer as n=19.

I recognise that some questions in C1 books require a calculator, however, this question can be done without.

If in doubt always take one with you. If they aren't allowed, just have a word with an invigilator and leave it under your chair or in your bag.

In this case, I'm assuming that the others are right that they aren't allowed, but otherwise there's nothing to lose.

Here is how the solution bank does it:

They are clearly evaluating using a calculator.

i just looked at 2011 the pastpapers and it says no calculator
but this calculation needs a calculator

The questions in the exam will usually involve simple calculations, so you won't need to use a calculator.

This question is from the book, the book contains a few questions which require a calculator.

Nothing to lose apart from the right to sit the exam for attempting to bring prohibited equipment into the exam hall.

OP, if you are confused by the conflicting messages in this thread ...

a) ask your teacher (although he or she will have certainly patiently explained at least 10 times already that Core 1 is a non-calculator exam)

b) read the specification (any A Level Awarding Body will be fine as they are all the same in this regard)

c) look at the front-cover of any Core 1 past paper
