Boolean Algebra is a mathematical technique that provides the ability to algebraically simplify logic expressions. These simplified expressions will result in a logic circuit that is equivalent to the original circuit, yet requires fewer gates.. Algebra. Huntington’s Postulates. Truth Tables. Graphic Symbols.

Boolean . operation can be further mapped into operations using bits and bytes. The most basic idea of Boolean Logic can be explained using logic gates. When the logic required becomes complex, these logic gates can be combined into more complex forms to get the required output. Joseph Busch and Vivian Bliss. Agenda. Pre-defined Boolean Queries.
