    its very easy dear.like general multiplications binary multiplications are also carried out...you need to carry out the addition in binary format i.e.,
    0 + 1=1 carry 0
    0 + 0=0 carry 0
    1 + 0=1 carry 0
    1 + 1=0 carry 1....like wise the multiplications are carried out...
    for eg..
    1 1 1 1
    * 1 1
    ______________
    0 0 1 1 1 1
    +1 1 1 1
    ______________
    1 0 1 1 0 1
    this is the required multiplication...
    hope this will help you

    Exactly praveena first of all convert 12 and 13 to its corresponding binary forms...
    i.e.,
    for 12 it is 1100
    for 13 it is 1101
    then apply the same rule as described previously...
    1 1 0 0
    * 1 1 0 1

    this is the required solution...hope this may help you
