How to Use Maths Shortcut Tricks for Competitive Exams

Simply reading shortcut methods is not enough. Candidates should understand the underlying concepts and practise applying each method to different questions.

Follow this approach:

1. Understand the basic concept: Learn the standard mathematical method before using shortcuts.

2. Learn important formulas: Maintain a separate formula notebook.

3. Practise calculation techniques: Work on multiplication, division, fractions and percentage conversions.

4. Solve topic-wise questions: Complete one chapter before moving to another.

5. Compare methods: Solve the same question using both the traditional and shortcut methods.

6. Maintain accuracy: Do not sacrifice correct answers just to save time.

7. Revise regularly: Revisit difficult formulas and questions.

Important Maths Shortcut Tricks for Quick Revision

Here are some useful calculation techniques that candidates can practise alongside their mathematics books.

Multiplication by 5

To multiply an even number by 5, divide it by 2 and multiply the result by 10.

Example:

Multiplication by 25

Divide the number by 4 and multiply by 100.

Example:

Multiplication by 11

For a two-digit number, add its digits and place the sum between them, carrying when necessary.

Example:

Percentage Calculation

To calculate 10% of a number, move the decimal point one place to the left.

Example:

10% of 750 = 75.

Multiplication by 9

Multiply a number by 10 and subtract the original number.

Example:

These methods are useful for mental calculation, but candidates should practise them with different numbers to avoid calculation errors.
