GCSE Maths: Using a Calculator
Use a scientific calculator accurately, including fractions, powers and memory. Practise it with adaptive questions for AQA, Edexcel, OCR and Eduqas.
What you need to know
The concepts examiners test on using a calculator, and what each one is really asking.
Where marks get lost
The exam technique that separates a correct method from a correct answer.
- Typing an expression left to right without brackets, so the calculator applies BIDMAS differently from what you meant
- Rounding partway through and retyping the rounded value, which loses accuracy by the final answer
- Reading a standard-form display such as 4.5 x 10 to the 7 as a plain 4.5
- Leaving the calculator in the wrong angle mode for trigonometry
Using a Calculator questions students ask
Is Using a Calculator on the Foundation paper?
Yes. Using a Calculator appears at both Foundation and Higher tier, though Higher papers take it further.
What should I know before starting Using a Calculator?
It builds on Order of operations (BIDMAS) and Rounding and estimation and Standard form. If those feel shaky, practise them first — Using a Calculator questions assume them.
What is the most common mistake in Using a Calculator?
Typing an expression left to right without brackets, so the calculator applies BIDMAS differently from what you meant.
Which exam boards cover Using a Calculator?
All four we support — AQA, Edexcel, OCR and Eduqas. GCSE Maths subject content is set by the DfE, so the topic is common to every board; what changes is the paper structure and the grade boundaries.
