Boolean algebra differs in a major way from ordinary algebra in that boolean constants and variable are allowed to have only two possible values 0 or 1. A Boolean variable is a quantity that may at different times be equal to either 0 or 1.

Boolean algebra is used to express the effects that various digital circuits have on logic inputs, and to manipulate logic variable for the purpose of determination of the best method for performing a given circuit function.

Because of possibility of only two variables boolean algebra is relatively easy to work with as compared to ordinary algebra. It have only 3 basic operations:

1. Logical Addition- OR

2. Logical Multiplication- AND

3. Logical Complimentation- NOT
