WebDe Morgan: a very useful rule, especially when coding: A · B = A ＋ B A ＋ B = A · B Let us look at each in turn: A · B = A ＋ B "not x and not y = not (x or y)" Example: Small · Blue = Small ＋ Blue Example: "I don't want mayo and I don't want ham" Is the same as "I don't want (mayo or ham)" And the other De Morgan rule: A ＋ B = A · B WebNov 23, 2015 · Generalized DeMorgan's Law proof. We wish to verify the generalized law of DeMorgan ( ⋃ i ∈ I A i) c = ⋂ i ∈ I A i c. Let x ∈ ( ⋃ i ∈ I A i) c. Then x ∉ ⋃ i ∈ I A i and x ∉ A i for i ∈ I, and so x ∈ A i c for all i. Hence x ∈ ⋂ i ∈ I A i c. We have shown that ( ⋃ i ∈ I A i) c ⊂ ⋂ i ∈ I A i c. We must ...
