Why is the complement of complement true? Something always feels wrong. I think there will be mistakes. I asked God to give me an explanation, preferably a mathematical formula.
(1) If the truth value y is positive, [Y] complement =Y, then find the complement or y;
(2) If the truth value y is negative, [Y] complement = modulus+y.
For example, the word length is 4 digits, the truth value Y =-10 1b, and the modulus = 10000B.
