Annulment: A AND 0 = 0A · 0 = 0
Annulment: A OR 1 = 1A + 1 = 1
Idempotent: A AND A = AA · A = A
Idempotent: A OR A = AA + A = A
Complement: A AND NOT A = 0A · A' = 0
Complement: A OR NOT A = 1A + A' = 1
Double Negation: NOT (NOT A) = AA'' = A
Commutative: A AND B = B AND AA · B = B · A
Commutative: A OR B = B OR AA + B = B + A
Associative: (A AND B) AND C = A AND (B AND C)(A·B)·C = A·(B·C)
Associative: (A OR B) OR C = A OR (B OR C)(A+B)+C = A+(B+C)
Distributive: A AND (B OR C) = (A AND B) OR (A AND C)A·(B+C) = A·B + A·C
Absorption: A OR (A AND B) = AA + A·B = A
Absorption: A AND (A OR B) = AA·(A+B) = A
De Morgan's: NOT (A AND B) = NOT A OR NOT B(A·B)' = A' + B'
De Morgan's: NOT (A OR B) = NOT A AND NOT B(A+B)' = A' · B'
