03: MULTIPLY 2-DIGIT NUMBER BY 11

__SUTRA (Algorithm):__

Push the SUM of Digits

in between the Digits

(Only if SUM of digits is 9 or less)
### Demonstration (1): 32 x 11 = ?

3 + 2 is 5;

Push this between 3 & 2; get 352.

So, in one line,

**32 x 11 = 352**.

### Demonstration (2): 43 x 11 = ?

4 + 3 is 7;

Push this between 4 & 3; get 473.

So, in one line,

**43 x 11 = 473**.

#### Verify The following Examples:

- 52 x 11 = 572
- 37 x 11 = 3 + 7 = 10,

so NOT this method!

- 24 x 11 = 264
- 63 x 11 = 693
- 42 x 11 = 462
- 35 x 11 = 385
- 75 x 11 = 7 + 5 = 12,

so NOT this method!

- 81 x 11 = 891
- 45 x 11 = 495
