Maths made easy

Vedic Mathematics is interesting and has many Sutras (Rules).

For example,

If you want to find the square of 65, you can employ the Ekadhikena Purvena sutra ("By one more than the one before").

The rule says since the first digit is 6 and the second one is 5, you will first have to multiply 6 and (6 +1), that is 6 X 7, which is equal to 42.

Then multiply 5 with 5, which is 25.

Hey Presto! The answer is 4225.

Now, you can try this method to find the squares of all numbers ending with 5.
