The Laws of Null Class (MA182E)

The sum of an element and the null class is equivalent to the element. The product consisting of an element and the null class is equivalent to the null class. The equivalent logic circuits are shown in Figure 1.

Laws of Null Class:

a + 0 = a

a x 0 = 0

 

Mathematic Notation:

a ∪ 0 = a

a ∩ 0 = 0

 

Logic Notation:

a ∨ 0 = a

a ∧ 0 = 0
