Boolean algebra
Boolean algebra is a mathematical analysis of logic invented by George Boole, an English mathemtaician, in the 19th century.
It has emerged as modern analytic tool in connection with the design of digital computer circuits.
Boolean algebra is a system that deals with variables that have only two possible values (true and false originally; on and off in modern usage). Only three operations are permitted in Boolean algebra the logical OR, the logical AND, and negation (or complementation).
Logical OR is usually represented by + (sometimes by a U shaped symbol called a 'cup' or by a V ) and is similar but not identical to addition.
Logical AND is usually represented by a dot (sometimes by an inverted 'cup' called a 'cap' or by an inverted V) and is similar to multiplication.
