This has the consequence that there are two reperesentations for zero, either all zeros or all ones. ... 000...00011 = +3 000...00010 = +2 000...00001 = +1 000...00000 = +0 111...11111 = -0 111...11110 = -1 111...11101 = -2 111...11100 = -3 ... Naive logic for ones complement addition might easily conclude that -0 + 1 = +0. The twos complement avoids this by using all ones to represent -1.
