Question

How to find the square of a number less than 75?

Answer 1

Helloo!!

Step 1. Find the difference between 50 and the number you want to square.

Condition 1: If the number to be squared is greater than 50

Step 2. Add that many 100s to 2500 (which is the square of 50)

Step 3. Then add the square of the difference to the result of step 1

Condition -2: If the number is less than 50

Step 2. Subtract that many 100s to 2500.

Step 3. Then add the square of the difference to the result of step 1

Im taking an Example of 67

Step 1. Difference of 67 and 50 = 67-50 = 17
Step 2. This number is greater than 50. So add 1700 to 2500 = 4200
Step 3. Add square of 17 to step 2.

solution :: 4200+ 289 = 4489

hope it helps
