Choosing the right calculator for A Level Further Maths is important — the right model can make complex calculations quicker, reduce errors, and help you work more efficiently in exams.

Your choice should meet your exam board’s requirements and give you the functions needed for advanced topics like matrices, complex numbers, and statistical distributions.

Exam board requirements

All UK A Level exam boards (AQA, Edexcel, OCR) allow calculators with advanced functions, provided they cannot do symbolic algebra (CAS — Computer Algebra Systems) such as solving equations exactly or performing algebraic manipulation.

Always check your specific board’s specification and the instructions for your exam series to make sure your calculator is permitted.

Recommended models for A Level Further Maths

The most commonly recommended calculators for A Level Maths and Further Maths are:

• Casio fx-991EX ClassWiz: Affordable, non-programmable, and packed with functions for statistics, matrices, and complex numbers.
• Casio fx-CG50: A more advanced graphing calculator with high-resolution display, great for visualising graphs and exploring functions (also permitted in A Level exams).

Functions you’ll need for Further Maths

• Matrix calculations (addition, multiplication, determinants, inverses).
• Complex number operations (modulus, argument, rectangular and polar forms).
• Statistical functions (probability distributions, regression analysis).
• Equation solving (numerical solutions to polynomials and simultaneous equations).
• Graph plotting (for certain models).

Should I get a graphing calculator?

A graphing calculator like the fx-CG50 can be very helpful for visual learning and quick checking of functions, but it’s not essential. Many students succeed with a scientific calculator like the fx-991EX, especially if cost is a factor.

Final thought

The Casio fx-991EX is a safe, cost-effective choice for most students. If you want extra visual tools and can afford it, the fx-CG50 is an excellent upgrade. Whichever you choose, make sure you’re confident using every feature well before exam day.
