Why is showing working important in GCSE Maths?

Showing working is important because students can often earn method marks even if the final answer is wrong. It also helps reduce careless mistakes.

Do you need to show working for every GCSE Maths question?

For one-mark questions, a final answer may be enough. For multi-mark questions, students should normally show clear working so the examiner can follow the method.

Can you get marks if your final answer is wrong?

Yes. In many GCSE Maths questions, method marks are available for correct steps even if the final answer is incorrect.

Showing Working in GCSE Maths

Showing working is one of the easiest ways to improve your GCSE Maths exam marks. Even if your final answer is wrong, clear working can help you earn method marks. It also makes your thinking easier to check and helps you avoid simple mistakes.

Exam tip: For any question worth more than one mark, assume the examiner wants to see your method. A correct answer with no working can be risky, especially in longer problem-solving questions.

What does showing working mean?

Showing working means writing down the important steps between the question and the answer. This may include calculations, equations, diagrams, substitutions, angle facts, units or short explanations.

Why method marks matter

Many GCSE Maths questions are marked in stages. This means you may get credit for choosing the correct method, even if you make an arithmetic error later.

Common mistake: A common mistake is doing all the working in your head and only writing the final answer. If the answer is wrong, the examiner may not be able to award method marks.

Example: showing working for a percentage question

Question: Find 35% of 180.

10% of 180 = 18
30% of 180 = 54
5% of 180 = 9
35% of 180 = 54 + 9 = 63

Answer: 35% of 180 is 63.

Example: showing working for an equation

Question: Solve 3x + 7 = 22.

3x + 7 = 22
3x = 22 - 7
3x = 15
x = 5

Answer: x = 5
