# Vedic math trick to check multiplication

Vedic maths is the ancient mathmematics discovered from the vedas by Sri Bharati Krsna Tirthaji. My Salutations to the Swamiji for providing us with such a useful and magical tool to solve complex mathematical problems. Vedic math trick to check multiplication is one such amazing trick. This Vedic math trick is an easy method to check if the multiplication of any two given numbers is done correctly.

## Vedic math trick to check multiplication steps

Let us now see the how it is done in the steps below.

Step 1:Find the sum of the digits of the numbers to be multiplied separately.

Step 2:Find the sum of the digits of the answer you got on multiplying each of the numbers.

Step 3:Multiply the results obtained in step 1 and find its sum of digits.

Step 4:Compare the sum of digits obtained in step 2 with the sum of the digits obtained in step 3.
If both are same then it means you have multiplied correctly.

Examples
Let us consider an example to understand better

Example 1: 105 x 140=14700

We want to check whether 14700 is the correct answer.
Here is how we can check it
Step 1:Finding sum of the digits of 105
105=1+0+5=6
Finding sum of digits of 140
140=1+4+0=5
Step 2:Finding sum of digits of the answer 14700
14700=1+4+7+0+0=12=1+2=3

Step 3:Multiplying the results obtained in step 1 we get,
6 x 5=30
finding sum of digits of 30
30=3+0=3

Step 4:Comparing result obtained in step 2 with result obtained in step 3 we notice that
Sum of digits in the both the cases is 3.

Hence, we can conclude that our multiplication is right and we arrived at the correct answer.
