Ekādhikena Pūrveṇa
Meaning: By one more than the previous one
Example: 65²
- The part before the 5 is 6.
- Multiply it by one more than itself: 6 × 7 = 42.
- Write 25 after it.
Answer: 4225
Take the digits before the final 5 and multiply them by the next number up. Then write 25 at the end. It works for any number ending in 5: 115² → 11 × 12 = 132, so 13225.
