Splitting

Quick calculations can be performed more easily if the numbers are split into more “manageable parts”. The best part of Splitting is that it helps us do the calculations mentally and can be applied to Addition, Subtraction, Multiplication and Division.

What is important in Splitting is to find the correct place to split so as to avoid carry.

Splitting can be used for any operation, viz. Addition, Subtraction, Multiplication, and Division.

I will explain you all with the help of examples for each of above cases.

Divisibility Check

Division is opposite of multiplication, and is repeated subtraction.

There is a unique pattern in division, that will help you to find whether any number is divisible by 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 or so on.

In this topic, we are going to learn how to check if a number is divisible by any of the above numbers without actually dividing it.

Let us compare the Traditional way of divisibility check with Vedic way.

Is 24567890 is divisible 3?

Traditional way:

The traditional way is very lengthy and takes time to check divisibility.

Vedic Way:

Check if sum of all digits of this number is divisible by 3.

Sum of digits = 2+4+5+6+7+8+9+0 = 41

Since 41 is not divisible by 3, so number 24567890  is also not divisible by 3.

In this topic, we are going to cover divisibility check by numbers 2, 3, 4, 5, 6, 7, 8, 9, and 10.
