Trick for Multiplication by 11 – Vedic Mathematics Method

Hi friends, in this Vedic Mathematics tutorial I am going to share How to multiply any number by 11 quickly. Just follow some simple steps and you will get your answer in a couple of seconds.

1) Multiply 2 digit number by 11

Let us multiply 72 by 11 using Vedic Mathematics trick.

Step 1: Split 72 as follows:

7_2

Step 2: Add 7 and 2, and write addition in between 7 and 2. So will get our answer as

792

Thus 72*11=792

Now, what if addition becomes two digit number. In such case, we just need to add 1 in the adjacent left digit. Let us take another example for this condition.

Multiply 85 by 11.

Step 1: Split 85 as follows:

8_5

Step 2: Add 8 and 5 and write addition in between them. But here addition becomes 13 and if we write 13 in between 8 and 5 answer become 8135 which is wrong. So in such situations, we need to write only 3 (from 13) and add 1 in 8. See below example.

2) Multiply 3 digit number by 11

Let us multiply 345 by 11

Step 1: Split 345 as follows

3 _ _ 5

Step 2: Add  (3+4) and (4+5) and write in between 3 and 5. So we will get our answer as

3795

Thus 345*11=3795

Now, what if addition becomes two digit number. In such case, we just need to add 1 in the adjacent left digit. Let us take another example for this condition.

Multiply 849 by 11

Step 1: Split 849 as follows

8_ _9

Step 2: Add (8+4=12) and (4+9=13) and write in between 8 and 9. But here addition is two digit numbers (12 and 13) so we need to add 1 in adjacent left digits as follows.
