Complement Law

0 Questions 1241 Views

It states that when the sum is performed between a variable and its complement, the result is 1. Likewise, when a multiplication is performed between a variable and its complement, the result is zero.
i.e.,
➡ A + A' = 1
➡ A.A' = 0
Proof:

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

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= AProof: Hence, 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
