Multiply by 11 | 16 Jul 2009
 
Result when we multiply 12345678901234567890123456789012 by 11.

Note : The answer should not be in the exponential form as we get in Windows Scientific calculator but it should be the complete figure upto the last digit.

Ohh My God but I would tell you something very simple method which would be good for learning as well.

For multiplication of 11 use the following technique

123 x 11
Consider the number as 01230
And answer would be
Code:

0+1 | 1+2 | 2+3 | 3+0
 1  |  3  |  5  | 3

How we get this

123
x11
===
0123
123x
===
1353

So applying same on the number

012345678901234567890123456789012
12345678901234567890123456789012x
==========================
