🪷 Vedic Maths Tricks for Kids: 8 Sūtras Made Simple
Vedic Mathematics is a set of mental-calculation methods described by Bharati Krishna Tirtha in the 20th century, organised around 16 short sūtras (word-formulas). Children love them because they turn long sums into one-line puzzles. Here are eight that work brilliantly for kids — with examples you can try right now.
1. Squares ending in 5 — Ekādhikena Pūrveṇa
“By one more than the one before.” Take the digits before the 5 and multiply by one more than itself, then write 25. 65²: 6 × 7 = 42 → 4225.
2. Same tens, ones adding to 10 — Antyayordaśake’pi
For 43 × 47 (tens both 4, ones 3 + 7 = 10): 4 × 5 = 20 on the left, 3 × 7 = 21 on the right → 2021.
3. Multiply near 10 — Nikhilam
8 × 7: 8 is 2 below 10, 7 is 3 below 10. Cross-subtract: 8 − 3 = 5 (tens). Multiply the gaps: 2 × 3 = 6 (ones) → 56. Great for children who find the 6–9 times tables tricky.
4. Multiply near 100 — Nikhilam
96 × 97: gaps 4 and 3. Left: 96 − 3 = 93. Right: 4 × 3 = 12 → 9312. Above 100 it works with adding: 103 × 107 → 110 | 21 → 11021.
5. Vertically and crosswise — Ūrdhva-Tiryagbhyām
The general method for any multiplication. 23 × 41: right digits 3 × 1 = 3; cross 2 × 1 + 3 × 4 = 14; left 2 × 4 = 8. So 8 hundreds + 14 tens + 3 = 943.
6. All from 9 and the last from 10 — Nikhilam Navataśćaramam Daśataḥ
1000 − 368: 9 − 3 = 6, 9 − 6 = 3, 10 − 8 = 2 → 632. No borrowing at all — perfect for working out change.
7. Times 99 — Ekanyūnena Pūrveṇa
“By one less than the one before.” 45 × 99: left is 45 − 1 = 44, right is 99 − 44 = 55 → 4455.
8. Checking answers with digit sums — Beejank
Add digits until one digit remains (the digit root). For 23 × 41 = 943: roots 5 × 5 = 25 → 7, and 943 → 16 → 7. They match, so the answer is very likely right. If they don't match, it's definitely wrong.
How to practise
Learn one sūtra at a time, watch a worked example, then do short practice sets. BeadBop's Mind Tricks module has a step-by-step “watch it work” mode and a “show me the trick” button on every practice question.
Quick answers
What is Vedic maths?
Vedic maths is a collection of mental-calculation techniques based on 16 short word-formulas (sūtras), popularised by Bharati Krishna Tirtha's 1965 book.
Is Vedic maths good for kids?
Yes — the tricks make multiplication, squaring and subtraction faster and more fun, and build confidence. They work best alongside a solid understanding of place value.
At what age can children learn Vedic maths?
Simple tricks like times 11 and squares ending in 5 suit children from about age 8; Nikhilam and vertically-and-crosswise suit ages 9 and up.
