Introduction to the 5 Rules of Vedic Maths for Fast Mental Calculation
Vedic Maths is an ancient Indian method of mental calculation known for its speed, accuracy, and simplicity. Using the 5 basic rules of Vedic Maths, learners can master quick calculation methods, shortcut techniques, and time-saving tricks for solving math problems. These mental math strategies are widely used in school math, daily calculations, competitive exams, and by professionals. Vedic Maths improves numerical ability, enhances concentration, and builds strong arithmetic skills for students of all levels.
Rule 1: Urdhva Tiryakbhyam – The Vertically and Crosswise Method for Fast Multiplication
Meaning: “Urdhva Tiryakbhyam” is a Sanskrit sutra from Vedic Maths that means “Vertically and Crosswise.”
This powerful multiplication technique is one of the most effective and commonly used Vedic Maths tricks for fast calculation. It simplifies the process of multiplying numbers using a logical, visual cross-pattern and is ideal for students, professionals, and competitive exam aspirants who need to solve problems quickly and accurately.
The Vertically and Crosswise rule helps you perform quick multiplication of two-digit and multi-digit numbers without relying on the traditional method. This Vedic Maths shortcut enhances mental calculation, reduces error, and builds math confidence in both academic and real-life scenarios.
Example: Multiply 23 × 12 Using Vertically and Crosswise
Example: Multiply 23 × 12 Using Vertically and CrosswiseStep 1: Multiply the unit digits → 3 × 2 = 6
Step 2: Cross-multiply and add → (2 × 2) + (3 × 1) = 7
Step 3: Multiply the tens digits → 2 × 1 = 2
Final Answer = 276
This Vedic Maths method is fast, easy to learn, and ideal for mental math practice, math speed improvement, and even daily calculations such as billing or budgeting.
Why This Rule Matters
Speeds up basic multiplication
Builds strong mental arithmetic skills
Essential for mastering the 5 rules of Vedic Maths
Perfect for Vedic Maths for students and math for competitive exams
Boosts confidence in solving math problems quickly
Reduces dependency on calculators
Improves performance in aptitude tests, school math, and entrance exams
Supports mental agility and quick decision-making
Rule 2: Nikhilam Navatashcaramam Dashatah – Multiply Numbers Near Base 10 Quickly
Meaning: “Nikhilam Navatashcaramam Dashatah” is a Sanskrit sutra that means “All from 9 and the last from 10.”
This Vedic Maths rule is especially helpful for multiplying numbers that are close to base values like 10, 100, 1000, etc. It reduces long multiplication steps into a quick and mental calculation method using simple subtraction and cross-multiplication.
The Nikhilam method is perfect for students preparing for competitive exams, professionals doing quick calculations, or anyone looking to improve math speed and accuracy in daily life. It is one of the most powerful Vedic Maths shortcuts that makes multiplication near base numbers incredibly fast.
✅ Example: Multiply 97 × 96 Using Nikhilam Navatashcaramam Dashatah
Step 1: Find how far each number is from the base 100:
97 is 3 less → −3
96 is 4 less → −4
Step 2: Cross-subtract:
97 − 4 or 96 − 3 = 93
Step 3: Multiply the deviations:
(−3) × (−4) = 12
🔹 Final Answer = 9312
This trick works because the numbers are close to 100, allowing you to calculate quickly using basic subtraction and multiplication.
✅ Why This Rule Matters
Best for multiplying numbers close to 10, 100, 1000
Speeds up calculation using base value tricks
Useful in mental math and competitive exams
Builds confidence in number manipulation
Ideal for banking, SSC, and school-level aptitude
A key part of mastering the 5 Vedic Maths rules
Reduces complex problems into simple two-step solutions
Rule 3: Paravartya Yojayet – Transpose and Adjust for Easy Division and Algebra
Meaning: “Paravartya Yojayet” is a Sanskrit sutra that means “Transpose and Adjust.”
This Vedic Maths rule is primarily used for quick division, simplifying algebraic expressions, and solving equations mentally. It helps in transforming a complex problem into a manageable one by intelligently rearranging and adjusting values. It’s an essential shortcut in Vedic Maths, especially in competitive exams and for students who want to reduce calculation time.
Example: Divide 1 by 9 using Paravartya Yojayet
Let’s apply the method to find the decimal of 1 ÷ 9.
Step 1: Use the standard Vedic division formula.
Step 2: Adjust and repeat the pattern using the divisor’s complement.
Result: 1 ÷ 9 = 0.111… (repeating decimal)
Though this is a basic example, the rule extends to algebraic cases too—like solving equations of the form:
(x + 3)/(x – 2) = 5, by transposing and adjusting quickly to isolate x.
Why This Rule Matters
Makes division fast and efficient
Helps solve algebra problems mentally
Great for competitive exams like SSC, IBPS, CAT
Saves time in simplifying fractions and equations
Ideal for Vedic Maths students aiming for speed
A core part of the 5 rules of Vedic Maths
Rule 4: Vinculum Process – Use Complements to Simplify Large Numbers
Meaning:
The Vinculum Process is a core concept in Vedic Maths that simplifies calculations by replacing large digits with their complements. Though it doesn’t originate from a specific sutra, it’s often derived from the Nikhilam Navatashcaramam Dashatah sutra (“All from 9 and the last from 10”).
This rule is extremely helpful in fast subtraction, easy division, and mental multiplication by converting numbers into smaller values. It makes mental calculations quicker, more accurate, and reduces cognitive load.
✅ Example: Subtract 1000 – 987 Using Vinculum Method
Instead of traditional borrowing:
Step 1: Find the complement of 987 from base 1000
→ 9−9 = 0, 9−8 = 1, 10−7 = 3Step 2: Final Answer = 13
You avoid borrowing and simplify mentally using complements.
✅ Why This Rule Matters
Makes large number subtraction easy
Removes the need for borrowing in subtraction
Helps in fast mental math and daily calculations
Simplifies Vedic Maths division and multiplication
Improves speed and accuracy in school and exams
Ideal for competitive exam aspirants
Builds number sense and confidence
Rule 5: Ekadhikena Purvena – Instantly Square Numbers Ending in 5
Ekadhikena Purvena” is a Sanskrit sutra that means “One more than the previous.”
This powerful Vedic Maths trick allows you to quickly square any number ending in 5 using mental calculation. It is one of the most popular and easy-to-learn rules for students, competitive exam aspirants, and anyone looking to improve their math speed.
This technique works especially well for 2-digit and 3-digit numbers ending in 5, saving time and avoiding lengthy multiplication.
✅ Example: Square 75 Using Ekadhikena Purvena
Step 1: Identify the number before 5:
75 → the number before 5 is 7
Step 2: Multiply that number by its next number:
7 × 8 = 56
Step 3: Add 25 at the end:
🔹 Final Answer = 5625
So, 75² = 5625 using a simple mental method!
