Such is the effect of Vedic Mathematics!

Write down 7. Then, write down the leftmost digit, 4.

Multiplying by 5, 25, or Multiplying by 5 is just multiplying by 10 and then dividing by 2. Note: To multiply by 10 just add a 0 to the end of the number. When two numbers differ by two their product is always the square of the number in between them minus 1. If two numbers differ by 4 then their product is the square of the number in the middle the average of the two numbers minus 4.

If the two numbers differ by 6 then their product is the square of their average minus 9. Squaring 2-digit numbers that end in 5 If a number ends in 5 then its square always ends in To get the rest of the product take the left digit and multiply it by one more than itself.

We get the rest of the product by multiplying 3 by one more than 3. You notice that the first digit is 4 in both cases.
