It is the extension of the trick that we done in last post check it

It is easy to multiply three digit with 11 verbally.

Consider the number that we want to multiply with 11 For e.g. 123

123* 11 = 1353

123

__*11__

__1 3 5 3__

The first digit from the right hand side will be the first digit of the number we are multiplying with 11

Here it 3 from 123

Second digit will be the sum of the first two digit of the number here it is 3 + 2 = 5

Third digit will be the sum of last two digit of the number here it is 2 + 1 = 3

last digit will be the last digit of the number here it is 1

So answer is 1353

**Note:-**Add carry from all these addition to next number

Check this E.g.

Multiplication of number 999 by 11

999

__× 11__

__10 989__

first digit = 9

Second digit = 9+9 = 18 so the number is 8 carry 1

third digit = 9+9 18 plus the carry + 1 equal to 19

fourth digit = 9 + 1 equal to 10

10989

Now calculate the value of 571×11, 589 ×11 and post
