Boolean Identities

When we calculate Boolean  sums, we have to use several types of Boolean Identities. These are helping to go to the last answer for the given question/sum. Without these we are unable to get the answer. Basically, there are 10 types of boolean identities and they are as following. 01. Law of double complement                                                    (A' )' = A 02. Idempotent Laws                       A + A = A                       A . A =A 03. Identity Law                       A + 0 =A                       A . 1 = A 04. Domination /Null/ Universal bound law                      A + 1 = 1                      A . 0 = 0 05. Commutative law                      A + B = B +A                      A . B = B . A 06. Associative Law                     A + (B+C) = (A+B) + C                     A . (B . C) = (A . B) . C 07. Distributive Law                     A . (B  + C) = (A . B) + (A . C)
