The English mathematician George Boole (1815-1864) invented mathematical, or symbolic, logic and uncovered the algebraic structure of deductive logic, thereby reducing it to a branch of mathematics.
The primary operations of Boolean logic are AND, OR, and NOT. Boolean logic is named after the 19th century English mathematician George Boole. As add, subtract, multiply, and divide are the primary operations of mathematics, the primary operations of Boolean logic are AND, OR, and NOT. These operators can be applied when searching electronic databases the library subscribes to such as Academic Search Premiere (EBSCOhost) and Lexis-Nexis.
