What is the correct way to represent a negative number in binary system?
I've seen two ways to represent a negative number in binary system. One approach is having the left-most digit as a signed bit, 0 indicating positive and 1 indicating negative. Another approach is taking 2'complement of a positive number to get its opposite number.

Usually you want to use the second approach. It allows you to keep your addition methods unchanged.
Google will answere this question for you ;-)
