Identity Law

0 Questions 2735 Views

It states that the sum of a variable and 0 is same as the variable itself. Likewise, multiplication of the variable with 1 is same as the variable itself.
i.e.,
➡ A + 0 = A
➡ A.1= A
Proof:

Hence, A + 0 = A & A.1= A.

Commutative Law

It states that the interchanging the order of operands in a Boolean equation doesn’t change its result.i.e., ➡ (A + B) = (B + A) ➡ A.B = B.AProof:Hence, (A + B) = (B + A) & A.B = B.A
