           Complementation Law /Negation Law:

           Law1: A·A’=0
           Proof:
           Case1: If A=0όA’= 1 So, A·A’=0·1=0
           Case2: If A =1όA’= 0 So, A·A’=1·0=0
           Double Negation Law:
           This law states that double negation of a variables is equal to the variable itself.
           Law1: A’’=A
           Proof:
           Case1: If A= 0όA’’= 0’’= 1’= A
           Case 2: If A = 1όA’’ =1’’=0’=A
           Any odd no.of inversion is equivalent to single inversion.
           Any even no.of inversion is equivalent to no inversion at all.
           Identity Law:

           Case1 : If A=1όA·1=1·1=1=A
           Case2 : If A=0όA·0=0·0=0=A
           Law2 : A+ 1 = 1
           Proof:
           Case 1: If A=1όA+1=1+1=1=A
           Case 2: If A=0όA+0=0+0=0=A
           Null Law:
           Case1: If A=1όA·0=1·0=0=0
           Case2: If A=0όA·0=0·0=0=0
           Law 2: A+ 0 = A
           Proof:
           Case 1: IfA=1όA+0=1+0=1=A
           Case 2 : IfA=0όA+0=0+0=0=A
           Absorption Law:
           Law1: A+AB = A
           Consensus Theorem:
           Theorem1:

           A·B +
