De morgan's law in maths

WebDe Morgan has suggested two theorems which are extremely useful in Boolean Algebra. The two theorems are discussed below. Theorem 1. The left hand side (LHS) of this theorem represents a NAND gate with inputs A and B, whereas the right hand side (RHS) of the theorem represents an OR gate with inverted inputs. This OR gate is called as … WebDe Morgan’s laws: (a) ¯ A ∪ B = ¯ A ∩ ¯ B, (b) ¯ A ∩ B = ¯ A ∪ ¯ B. Laws of the excluded middle, or inverse laws: A ∪ ¯ A = U, A ∩ ¯ A = ∅. As an illustration, we shall prove the distributive law A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C). We need to show that A ∪ (B ∩ C) ⊆ (A ∪ B) ∩ (A ∪ C), and (A ∪ B) ∩ (A ∪ C) ⊆ A ∪ (B ∩ C).
