Multiplying two 2-digit numbers (difference of 1)

Follow the following Steps:

1. Choose a 2-digit number.
2. Select a number either 1 smaller or 1 larger.
3. Square the larger number (multiply it by itself).
4. Subtract the larger number from the product.
   OR
5. Square the smaller number (multiply it by itself).
6. Add the smaller number to the product. Pick the easier one to square.

   Example-1:

1. If the first number is 76, choose 75 as the second number.
2. 75 × 75 = 5625 (square the smaller). 
3. 5625 + 75 = 5700 (add the smaller).
4. So 76 × 75 = 5700.

   Example-2:

1. If the first number is 32, choose 31 as the second number.
2. 32 × 32 = 1024 (square the larger). Remember how to
3. 1024 - 32 = 992 (subtract the larger).
4. So 32 × 31 = 992.
