2. Break Down Complex Problems
Breaking a difficult calculation into smaller steps makes it easier to solve mentally.
Example:
To calculate 47 + 36, break it down:
40 + 30 = 70
7 + 6 = 13
- Final answer: 70 + 13 = 83
Action Step:
- Practice breaking down addition, subtraction, multiplication, and division problems into manageable steps.

3. Use Number Bonds for Faster Addition
Number bonds are pairs of numbers that add up to a specific total (e.g., 10, 20, 100).
Example:
To calculate 78 + 25, use number bonds:
- 78 + 20 = 98
- 98 + 5 = 103
Action Step:
- Memorize number bonds for quick addition and subtraction.

4. Master Multiplication Tables
Knowing multiplication tables up to 12 is crucial for quick calculations in GCSE Maths.
Action Step:
- Practice multiplication tables using flashcards, apps, or quizzes until they become second nature.
- Use the finger method for the 9 times table and tricks like doubling for x4 and x8 tables.

5. Use Rounding and Adjusting for Estimations
Rounding numbers simplifies mental calculations, allowing you to adjust later for accuracy.
Example:
To calculate 48 × 5, round 48 to 50:
50 × 5 = 250
- Adjust: 250 – (2 × 5) = 240
Action Step:
- Practice rounding numbers before multiplying, dividing, or estimating answers.

6. Get Comfortable with Percentages
Percentages appear frequently in GCSE Maths, and solving them mentally can save time.
Example:
To find 15% of 60:
10% of 60 = 6
5% of 60 = 3
15% of 60 = 6 + 3 = 9
Action Step:
- Memorize percentage shortcuts (e.g., 50% = half, 10% = move decimal one place, 25% = divide by 4).

7. Visualize Numbers for Faster Calculations
Many people struggle with mental math because they don’t visualize numbers effectively.
Action Step:
- Use number lines, grids, or mental images to picture calculations.
- Break numbers into place values (e.g., hundreds, tens, ones) to simplify operations.

To estimate 49 × 21, round to:
50 × 20 = 1000
If your exact answer is close to 1000, you know it’s correct.
Action Step:
- Practice estimating before calculating exact answers.
