It's like a clock, and you can always find the right value in the range you're looking for in a round!The 2+126 is obviously the equivalent of a clock turning round, and because the sign bit is involved in the calculation, just as the highest level of overflow to form the correct results.Since the anti-code can be subtraction into addition, now the computer uses the complement it? Why add 1 on the basis of anti-
