To perform a 2's complement take the reverse of the number to be subtracted, add one to the new second term, add this new term to the original term and you get a binary number, which is one digit longer than the digits of numbers involved in the problem. That is, when you involve two binary numbers which are 3 digits each, then the resulting binary number would be a four digit number. Discard the first digit to get the final answer.
