INTRODUCTION:

In 1854, George Boole, an English mathematician, proposed algebra for symbolically representing problems in logic so that they may be analyzed mathematically. The mathematical systems founded upon the work of Boole are called

Boolean algebra in his honor.

The application of a Boolean algebra to certain engineering problems was introduced in 1938 by C.E. Shannon.

For the formal definition of Boolean algebra, we shall employ the postulates formulated by E.V. Huntington in 1904.

**Fundamental postulates of Boolean algebra:**

The postulates of a mathematical system forms the basic assumption from which it is possible to deduce the theorems, laws and properties of the system.

The most common postulates used to formulate various structures are—

i) Closure:

A set S is closed w.r.t. a binary operator, if for every pair of elements of S, the binary operator specifies a rule for obtaining a unique element of S.

The result of each operation with operator (+) or (.) is either 1 or 0 and 1, 0 ЄB.

ii) Identity element:

A set S is said to have an identity element w.r.t a binary operation * on S, if there exists an element e Є S with the property
