Boolean Algebra

Boolean algebra is a branch of mathematics where the values are strictly true or false (usually denoted as 1 and 0).

It is the foundation of digital logic circuits and computer programming conditions.

The Three Basic Operations

AND: Returns true ONLY if BOTH inputs are true.
OR: Returns true if AT LEAST ONE input is true.
NOT: Reverses the input. True becomes false, false becomes true.
