5 Tips for Speed Math

Speed is crucial in aptitude exams. Here are 5 tricks to boost your calculation speed:

1. Memorize Tables, Squares, and Cubes

This is non-negotiable. Memorize tables up to 30, squares up to 50, and cubes up to 20.

2. The 11 Rule

To multiply any two-digit number by 11, just add the two digits and place the sum in the middle. (e.g., 34 * 11 = 3 (3+4) 4 = 374).

3. Base Multiplication

Use the base 100 method to quickly multiply numbers close to 100 (e.g., 104 * 105).

4. Digital Root

Use digital roots (sum of digits) to quickly verify calculated answers in multiple-choice questions without doing the full calculation.

5. Daily Practice

Spend 15 minutes daily purely on calculation apps or speed sheets.
