Boolean algebra derives its name from the mathematician George Boole. Symbolic Logic uses values, variables and operations :
           
       

    True is represented by the value 1.
    False is represented by the value 0.

       

Variables are represented by letters and can have one of two values, either 0 or 1. Operations are functions of one or more variables.
       

    AND is represented by X.Y
    OR is represented by X + Y
    NOT is represented by X' . Throughout this tutorial the X' form will be used and sometime !X will be used.

       

These basic operations can be combined to give expressions.
           
      

Example :
           



    X
    X.Y
    W.X.Y + Z
