Finding Square in seconds and Tricks
Example 1: 25²
Step 1:
Take the unit digit (5) and square it.
5² = 25 → Write 5 in the unit place and carry over 2.
Step 2:
Multiply the tens digit (2), the unit digit (5), and 2.
2 × 5 × 2 = 20 → Add carry over (2) → Total = 22 → Write 2 in the tens place and carry over 2.
Step 3:
Square the tens digit (2² = 4) and add the carry over (2).
4 + 2 = 6 → Write this in the hundreds place.
Final Answer: 625
Example 2: 36²
Step 1:
Take the unit digit (6) and square it.
6² = 36 → Write 6 in the unit place and carry over 3.
Step 2:
Multiply the tens digit (3), the unit digit (6), and 2.
3 × 6 × 2 = 36 → Add carry over (3) → Total = 39 → Write 9 in the tens place and carry over 3.
Step 3:
Square the tens digit (3² = 9) and add the carry over (3).
9 + 3 = 12 → Write this in the hundreds place.
Final Answer: 1296
