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