Vedic Mathematics: Learn 16 Sutras, Easy Tricks and Mental Maths
Discover simple calculation techniques, multiplication shortcuts, squaring methods, division strategies and practical mathematics exercises for students and beginners.
1. What Is Vedic Mathematics?
Vedic Mathematics is the name commonly given to a collection of mathematical techniques popularised by Swami Bharati Krishna Tirtha in the twentieth century. Many of these techniques use number patterns, complements, mental calculation and algebraic relationships to make selected calculations easier.
The methods can help learners explore arithmetic in different ways. Instead of relying on only one written procedure, students can learn to recognise patterns and choose a method that suits the problem.
Understand Patterns
Learn how numbers relate to one another.
Calculate Mentally
Practise useful mental arithmetic shortcuts.
Improve Accuracy
Check answers using alternative methods.
Build Confidence
Progress from simple examples to harder problems.
2. History and Background
Swami Bharati Krishna Tirtha lived from 1884 to 1960. He presented a system of mathematical techniques organised around short Sanskrit statements known as sutras. His book Vedic Mathematics was published in 1965, five years after his death.
The system became known for methods involving multiplication, complements, algebraic manipulation and mental calculation. Teachers subsequently developed lessons and exercises to help students practise these approaches.
The claimed ancient Vedic origins of the complete system remain a matter of historical discussion. Readers should distinguish the modern collection of techniques from independently documented achievements in the history of Indian mathematics.
Why is it popular today?
- Some methods are easy to demonstrate visually.
- Number patterns make arithmetic more engaging.
- Selected calculations can be completed with fewer written steps.
- Students can compare different approaches to the same problem.
- Short exercises are suitable for daily practice.
3. Benefits of Learning Vedic Mathematics
Better number sense
Complement methods encourage students to understand the distance between a number and a convenient base such as 10, 100 or 1,000.
Flexible calculation strategies
A student may use ordinary multiplication, a distributive expansion or a suitable shortcut. Comparing methods builds flexibility.
Useful examination practice
Mental arithmetic techniques may help with selected numerical aptitude questions. Students must still practise the actual examination syllabus and time limits.
More confidence with numbers
Starting with manageable examples and checking each answer helps learners become more comfortable with calculations.
Results depend on the learner, the method and the amount of practice. No shortcut guarantees perfect accuracy or success in every examination.

5. Easy Vedic Mathematics Techniques
Lesson 1: Multiply a number by 11
For a two-digit number, add its two digits and place the sum between the digits. If the sum is 10 or more, carry the extra value to the left.
Example: 32 × 11
Step 1: The digits are 3 and 2.
Step 2: Add them: 3 + 2 = 5.
Step 3: Put 5 between 3 and 2.
Example: 57 × 11
5 + 7 = 12.
Write 2 in the middle and carry 1 to the left.
Check: 57 × 11 = 57 × (10 + 1) = 570 + 57 = 627.
Lesson 2: Multiply numbers near 100
This method uses the Nikhilam complement idea. It works particularly neatly when both numbers are close to 100.
Example: 98 × 97
Step 1: Find the deficiencies from 100.
98 is 2 below 100; 97 is 3 below 100.
Step 2: Subtract crosswise.
98 − 3 = 95.
Step 3: Multiply the deficiencies.
2 × 3 = 6. Since the base is 100, write this as 06.
Answer: 9,506
Lesson 3: Multiply numbers near 1,000
Example: 996 × 994
996 is 4 below 1,000.
994 is 6 below 1,000.
Cross-subtract: 996 − 6 = 990.
Multiply deficiencies: 4 × 6 = 24.
Because the base is 1,000, the right-hand part must contain three digits: 024.
Answer: 990,024
Lesson 4: Vertically and crosswise multiplication
The Urdhva-Tiryagbhyam approach is a structured way to combine partial products. For two-digit numbers, it can be demonstrated in three stages.
Example: 23 × 14
Step 1 — Units: 3 × 4 = 12.
Write 2 and carry 1.
Step 2 — Crosswise: 2 × 4 + 3 × 1 = 11.
Add the carry: 11 + 1 = 12.
Write 2 and carry 1.
Step 3 — Tens: 2 × 1 + 1 = 3.
The same result follows from ordinary multiplication: 23 × 14 = 23 × (10 + 4) = 230 + 92 = 322.
Lesson 5: Square numbers ending in 5
A useful pattern allows numbers ending in 5 to be squared mentally.
Example: 35²
Step 1: Take the first digit, 3.
Step 2: Multiply it by the next integer: 3 × 4 = 12.
Step 3: Append 25.
Example: 85²
8 × 9 = 72.
Append 25.
Why does it work? If a number is 10a + 5, its square is 100a(a + 1) + 25. The pattern follows directly from algebra.
Lesson 6: Square a number near 100
Example: 103²
103 = 100 + 3.
Use (a + b)² = a² + 2ab + b².
103² = 100² + 2 × 100 × 3 + 3².
= 10,000 + 600 + 9.
Lesson 7: Multiply by 5
For an even whole number, divide by 2 and append a zero. For an odd whole number, subtract 1, divide by 2 and append 5.
Example: 246 × 5
246 ÷ 2 = 123.
Example: 137 × 5
137 − 1 = 136.
136 ÷ 2 = 68.
6. Multiplication Shortcuts
Distributive multiplication
Break one number into convenient parts. This is an ordinary mathematical property that also supports many mental arithmetic techniques.
Example: 48 × 25
25 = 100 ÷ 4.
48 × 25 = 48 × 100 ÷ 4.
= 4,800 ÷ 4.
Multiply 99 by a number
Example: 46 × 99
99 = 100 − 1.
46 × 99 = 46 × 100 − 46.
= 4,600 − 46.
Multiply 101 by a number
Example: 72 × 101
101 = 100 + 1.
72 × 101 = 7,200 + 72.
7. Squaring Numbers: More Examples
Square a number ending in 5
Square numbers near 50
Example: 48²
48 = 50 − 2.
48² = 50² − 2 × 50 × 2 + 2².
= 2,500 − 200 + 4.
Square numbers near 1,000
Example: 1,002²
1,002 = 1,000 + 2.
1,002² = 1,000,000 + 4,000 + 4.
These examples are applications of algebraic identities. Understanding why the identities work is more valuable than memorising answers.
8. Division Techniques
Division shortcuts can be useful when the divisor has a convenient relationship with a base. The following examples demonstrate simple ways to reorganise a calculation.
Divide by 5
Example: 1,240 ÷ 5
Dividing by 5 is equivalent to multiplying by 2 and dividing by 10.
1,240 × 2 = 2,480.
2,480 ÷ 10 = 248.
Divide by 25
Example: 3,600 ÷ 25
25 × 4 = 100.
Multiply the dividend by 4, then divide by 100.
3,600 × 4 = 14,400.
14,400 ÷ 100 = 144.
Divide by 125
Example: 5,000 ÷ 125
125 × 8 = 1,000.
5,000 × 8 = 40,000.
40,000 ÷ 1,000 = 40.
9. Algebra and Number Patterns
Vedic Mathematics lessons also encourage students to explore algebraic relationships. The following identities are fundamental mathematical tools that explain several shortcuts.
Identity 1: Square of a sum
Example:
Identity 2: Square of a difference
Example:
Identity 3: Difference of two squares
Example:
Identity 4: Multiplication by decomposition
Example:
These identities are part of standard algebra. They are especially useful when a number can be split into convenient components.

- Ignoring carrying: Carrying is necessary in multiplication by 11 and in vertically-and-crosswise multiplication.
- Using every trick for every problem: Choose the method that suits the numbers.
- Memorising without understanding: Learn why each procedure works.
- Skipping verification: Check important answers using a second method.
14. How Parents and Teachers Can Help
Parents and teachers can introduce mental arithmetic through short games, number cards, blackboard exercises and friendly competitions.
Begin with addition, multiplication tables and number patterns. Introduce one shortcut at a time. Ask students to explain their reasoning rather than rewarding speed alone.
Students should continue learning place value, fractions, decimals, algebra, geometry and mathematical reasoning through their regular curriculum. Alternative calculation techniques work best when they strengthen, rather than replace, these foundations.
