Introduction to Vedic Mathematics

Vedic Mathematics is an ancient system of mathematical techniques that originated in India. It is based on 16 Sutras (principles) and 13 Sub-Sutras (corollaries) that provide efficient and speedy methods for calculations. These methods are simple, flexible, and can be applied to a wide range of mathematical problems.

The 16 Sutras of Vedic Mathematics

Each sutra is a guiding principle for mathematical operations, offering concise and practical solutions:

1. Ekadhikena Purvena (By one more than the previous one)

2. Nikhilam Navatashcaramam Dashatah (All from 9 and the last from 10)

3. Urdhva Tiryagbhyam (Vertically and crosswise)

4. Paravartya Yojayet (Transpose and adjust)

5. Shunyam Saamyasamuccaye (When the sum is the same, that sum is zero)

6. Anurupyena (Proportionately)

7. Sankalana-vyavakalanabhyam (By addition and subtraction)

8. Puranapuranabhyam (By the completion or non-completion)

9. Chalana-Kalanabhyam (Differences and similarities)

10. Yaavadunam (Whatever the extent of deficiency)

11. Vyashtisamanstih (Part and whole)

12. Shesanyankena Charamena (The remainders by the last digit)

13. Sopaantyadvayamantyam (The ultimate and twice the penultimate)

14. Ekanyunena Purvena (By one less than the previous one)

15. Gunitasamuccayah (The product of the sum is equal to the sum of the product)

16. Gunakasamuccayah (The factors of the sum are equal to the sum of the factors)

The 13 Sub-Sutras of Vedic Mathematics

The Sub-Sutras extend the scope of the main Sutras and address specific calculations:

1. Anurupyena (Proportionately)

2. Shishyate Sheshasamjnah (The remainder remains constant)

3. Adyamadyenantya-mantyena (The first by the first and the last by the last)

4. Kevalaih Saptakam Gunyat (If one is in ratio, the other is zero)

5. Vestanam (By osculation)

6. Yavadunam Tavadunikritya Vargancha Yojayet (Whatever the deficiency, lessen it, and add the square of the deficiency)

7. Antyayordashake'pi (If the last digits add up to 10)

8. Antyayoreva (Only the last terms)

9. Samuccayagunitah (The sum is the product)

10. Lopanasthapanabhyam (By elimination and retention)

11. Gunitasamuccayah Samuccayagunitah (The product of the sum is the sum of the product)

12. Dhvajanka (On the flag)

13. Dvandva Yoga (The sum of the products in pairs)
