Sutra: Ekadhikena Purvena — "One more than the previous"
In traditional addition we add right to left. The Vedic approach adds left to right, giving you the most significant digit first — ideal for mental work.
Example: 347 + 286
When numbers are close to a base (10, 100, 1000), express them as base ± deviation and add the deviations. Much faster than column addition.
Example: 97 + 96
Group digits into pairs, add pairs simultaneously, then verify using the digit-sum (casting out nines) rule to catch errors instantly.
Example: 4532 + 3789
Multiply cross-wise, add, and place the result over the product of denominators. Faster than finding LCM for mental calculations.
Example: 2/3 + 3/5
Sutra: Nikhilam Navatascaramam Dasatah — "All from nine and the last from ten"
To subtract any number from a power of 10, subtract each digit from 9 except the last digit which is subtracted from 10. No borrowing required!
Example: 10000 − 3746
Find the ten's complement of the subtrahend and add. This turns any subtraction into addition — far less error-prone for mental maths.
Example: 523 − 178
Express both numbers relative to a chosen base, subtract the deviations, and adjust. Powerful for numbers near round figures.
Example: 1003 − 997
Work from left to right, subtracting digit by digit and adjusting as you go. Gives you the leading digit of the answer immediately.
Example: 862 − 375
Sutra: Urdhva-Tiryagbhyam — "Vertically and Cross-wise"
Multiply vertically then cross-wise. Write partial products in columns and carry. Works for any two 2-digit numbers.
Example: 23 × 41
When both numbers are close to 10, 100, or 1000 — use deviations. Multiply deviations together, cross-add for the main part.
Example: 97 × 96 (base 100)
To multiply any 2-digit number by 11, simply place the sum of its digits between the two digits. Expand the trick to larger numbers.
Example: 54 × 11
Sutra: Ekadhikena Purvena. For any number ending in 5, multiply the left part by (left part + 1), and append 25.
Example: 65²
Sutra: Paravartya Yojayet — "Transpose and Apply"
To divide by 9, bring down the first digit, add to the next, carry as you go. The last result is the remainder.
Example: 1234 ÷ 9
Divide by numbers like 11, 12, etc. — rewrite as (10 + r) and use the complement r to build the quotient digit by digit.
Example: 1234 ÷ 12
For multi-digit divisors, place the flag (extra digits of the divisor) above the dividend and subtract flag-products as you proceed left to right.
Example: 2135 ÷ 23
For 3-digit ÷ 2-digit, split the divisor and use the vertical-cross approach column by column to get both quotient and remainder simultaneously.
Example: 456 ÷ 12
