The 16 Sutras of Vedic Mathematics — Ancient Speed Math That Beats Calculators

Vedic Mathematics — 5000 Saal Purani Speed Math Jo Aaj Bhi Kaam Karti Hai

Vedic Mathematics is a system of 16 mathematical sutras (formulas) and 13 sub-sutras discovered by Swami Bharati Krishna Tirtha (Shankaracharya of Puri) from the Atharva Veda's appendix text — the Ganita Sutras. Published posthumously in 1965, this system offers mental calculation techniques that are dramatically faster than modern conventional methods.

Yeh koi magic nahi hai — yeh pure logical shortcuts hain jo India ke ancient scholars ne develop kiye the. Aaj bhi competitive exams (CAT, UPSC, Banking) mein lakhs of students Vedic Maths use karte hain speed badhane ke liye.

All 16 Sutras — Complete List With Explanations

Sutra 1: Ekadhikena Purvena (एकाधिकेन पूर्वेण)

Meaning: "By one more than the previous one"

This sutra is used for:

Squaring numbers ending in 5 (e.g., 75² = 5625)
Multiplying numbers whose first digits are the same and last digits add to 10 (e.g., 43 × 47)

Example — Square of 75:

Take the digit(s) before 5 → 7
Multiply by "one more than itself" → 7 × 8 = 56
Append 25 → 5625

That's it. 75² = 5625. Koi calculator nahi chahiye.

Example — Square of 105:

Digits before 5 → 10
10 × 11 = 110
Append 25 → 11025

Try it with the Vedic Math Calculator — type any number ending in 5 and watch the step-by-step breakdown.

Sutra 2: Nikhilam Navatashcaramam Dashatah (निखिलं नवतश्चरमं दशतः)

Meaning: "All from 9, the last from 10"

This is the most powerful sutra for multiplying numbers close to a base (10, 100, 1000, etc.).

Live Example — Multiply 97 × 96 in 3 Seconds:

Step 1: Choose base = 100 Step 2: Find deficiencies:

97 is 3 less than 100 → deficit = 3
96 is 4 less than 100 → deficit = 4

Step 3: Cross-subtract (either way gives same answer):

97 − 4 = 93 (or 96 − 3 = 93) → this is the left part

Step 4: Multiply the deficits:

3 × 4 = 12 → this is the right part

Step 5: Combine: 9312

97 × 96 = 9312. Verify on any calculator. Yeh 3 second mein ho gaya — bina pen-paper ke.

Another Example — 988 × 997:

Base = 1000
Deficits: 12 and 3
Cross-subtract: 988 − 3 = 985
Multiply deficits: 12 × 3 = 036 (pad to 3 digits for base 1000)
Answer: 985,036

Sutra 3: Urdhva-Tiryagbhyam (ऊर्ध्व-तिर्यग्भ्याम्)

Meaning: "Vertically and crosswise"

The general multiplication sutra. Works for any multiplication — not just numbers near a base.

Example — 23 × 14:

Vertical right: 3 × 4 = 12 → write 2, carry 1
Crosswise: (2 × 4) + (3 × 1) = 11 → add carry 1 = 12 → write 2, carry 1
Vertical left: 2 × 1 = 2 → add carry 1 = 3

Answer: 322

This method scales beautifully to 3-digit, 4-digit, and even larger numbers with the same cross-multiplication pattern.

Sutra 4: Paravartya Yojayet (परावर्त्य योजयेत्)

Meaning: "Transpose and adjust"

Used for division — especially when the divisor is slightly above a base (like 12, 102, 1003).

Example — 1225 ÷ 12:

12 is 2 more than base 10
Transpose: use −2 as the working divisor
Apply the flag division method
Result: 102 remainder 1

This sutra also applies to solving linear and simultaneous equations mentally.

Sutra 5: Shunyam Saamyasamuccaye (शून्यं साम्यसमुच्चये)

Meaning: "When the sum is the same, that sum is zero"

Used for solving equations where terms share a common factor or where the sum of numerators equals the sum of denominators.

Example: If (x + 3)(x + 5) = (x + 1)(x + 7)

Sum of constants on left: 3 + 5 = 8
Sum of constants on right: 1 + 7 = 8
Since sums are equal → x = 0 (the samuccaya is zero)

Sutra 6: Anurupye Shunyamanyat (आनुरूप्ये शून्यमन्यत्)

Meaning: "If one is in ratio, the other is zero"

Used in simultaneous equations. If the coefficients of one variable are in the same ratio as the constants, the other variable is zero.

Sutra 7: Sankalana-Vyavakalanabhyam (संकलन-व्यवकलनाभ्याम्)

Meaning: "By addition and subtraction"

Used for solving simultaneous equations by simple addition or subtraction of the equations rather than complex elimination.

Example:

3x + 2y = 18
3x − 2y = 6
Adding: 6x = 24 → x = 4
Subtracting: 4y = 12 → y = 3

Sutra 8: Puranapuranabhyam (पूरणापूरणाभ्याम्)

Meaning: "By completion or non-completion"

Used for completing the square in quadratic equations and for certain types of multiplication.

Example — Solve x² + 6x = 7:

Complete the square: x² + 6x + 9 = 16
(x + 3)² = 16
x + 3 = ±4
x = 1 or x = −7

Sutra 9: Chalana-Kalanabhyam (चलन-कलनाभ्याम्)

Meaning: "Differences and similarities"

Applied in factoring quadratic expressions and finding square roots of complex numbers. It involves sequential differential calculations.

Sutra 10: Yavadunam (यावदूनम्)

Meaning: "By the deficiency"

Specifically designed for squaring numbers near a base.

Example — Square of 96:

Base = 100, deficit = 4
Subtract deficit from number: 96 − 4 = 92
Square the deficit: 4² = 16
Answer: 9216

Example — Square of 1003:

Base = 1000, surplus = 3
Add surplus: 1003 + 3 = 1006
Square the surplus: 3² = 009
Answer: 1,006,009

Sutra 11: Vyashtisamanstih (व्यष्टिसमष्टिः)

Meaning: "Part and whole"

Used for complex equations involving cubes, higher powers, and the relationship between individual terms and their aggregate.

Sutra 12: Shesanyankena Charamena (शेषाण्यङ्केन चरमेण)

Meaning: "The remainders by the last digit"

Used for expressing fractions as recurring decimals and for divisibility tests.

Example — 1/7 as a decimal:

Using the last digit technique, you can generate the repeating pattern 142857 directly without long division.

Sutra 13: Sopaantyadvayamantyam (सोपान्त्यद्वयमन्त्यम्)

Meaning: "The ultimate and twice the penultimate"

Used for solving specific types of fraction equations and merger problems.

Sutra 14: Ekanyunena Purvena (एकन्यूनेन पूर्वेण)

Meaning: "By one less than the previous one"

Used for multiplying any number by a repunit (111, 1111, etc.) or numbers consisting entirely of 9s.

Example — 35 × 99:

Left part: 35 − 1 = 34
Right part: 100 − 35 = 65
Answer: 3465

Sutra 15: Gunitasamuchyah (गुणितसमुच्चयः)

Meaning: "The product of the sum is equal to the sum of the product"

Used as a verification technique. After multiplication, the digit-sum of the product should equal the product of the digit-sums of the factors.

Example — Verify 23 × 14 = 322:

Digit sum of 23: 2 + 3 = 5
Digit sum of 14: 1 + 4 = 5
Product of digit sums: 5 × 5 = 25 → digit sum = 7
Digit sum of 322: 3 + 2 + 2 = 7 ✅

Sutra 16: Gunakasamuchyah (गुणकसमुच्चयः)

Meaning: "The factor of the sum is equal to the sum of the factor"

The complement to Sutra 15 — used for verifying division and factoring results.
