Boolean

Branch of algebra in which the values of the variables are true and false

Boolean algebra is a branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0 respectively. It is used for logical operations and binary variables. Boolean algebra is fundamental in the development of digital electronics and computer science.

History

Boolean algebra was introduced by the English mathematician George Boole in his first book The Mathematical Analysis of Logic (1847) and set forth more fully in his An Investigation of the Laws of Thought (1854). The term "Boolean algebra" honors his work in the field.

Basic Operations

The basic operations of Boolean algebra are:

• AND (conjunction): The result is true if both operands are true.
• OR (disjunction): The result is true if at least one of the operands is true.
• NOT (negation): The result is the opposite of the operand.

Boolean Functions

A Boolean function is a function that delivers a Boolean value (true or false) as output. Boolean functions can be represented using truth tables, Boolean expressions, or logic gates.

Applications

Boolean algebra is widely used in:

• Digital circuits and logic design
• Computer programming
• Set theory
• Search algorithms in databases and search engines
