Question

how to find the square of any two numbers ​

Answer 1

Step 1: Add the last digit of the number you are trying to square to the entire number itself, creating your sum.

Step 2: Multiply the sum (step 1) by the first digit of the base number.

Step 3: Square the last digit of the base number.

Step 4: Append the square number (step 3) to the product calculated above (step 2).

For example: 32²

Base number: 32     First digit: 3      Last digit: 2

Step 1: 2 + 32 = 34

Step 2: 34 x 3 = 102

Step 3: 2² = 4

Step 4: 1024
