    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
    0+1 | 1+2 | 2+3 | 3+0
     1  |  3  |  5  | 3
    How we get this


    So applying same on the number


    Congrats hotnspicy
