One of the laws takes the form B − ⋃ A ∈ A A = ⋂ A ∈ A ( B − … De Morgan's Law consists of a pair of transformation rules in boolean algebra that is used to relate the intersection and union of sets through complements. There are two conditions that are specified under Demorgan's Law. These conditions are primarily used to reduce expressions into a simpler form. See more Demorgan's law can be used in boolean algebra as well as in set theory to simplify mathematical expressions. Suppose we have two sets A and B that are subsets of the universal setU. A' is the complement of A and B' is the … See more Let us understand De Morgan's Law with the help of a simple example. Let the universal set U = {7, 8, 9, 10, 11, 12, 13 }. The two subsets are given by A = {11, 12, 13} and B = {7, 8}. … See more In boolean algebra, we make use of logic gates. These logic gates work on logic operations. Here, A and B become input binary variables. … See more csvhelper read header row
