Why do computers store negative numbers as complements to their positive counterpart? Rather than a byte specifying the sign?
The math is easier to implement that way. Say you have -1 and 1 to add. Stored in two's complement form -1 is FFFF.
The Short Answer
The math is easier to implement that way. Say you have -1 and 1 to add. Stored in two's complement form -1 is FFFF. Add 1 and you get 10000, or 0000 ignoring the overflow. You don't need to do anything special just because one of the numbers is negative.
