Boolean algebra, and other forms of abstract propositional logic, are based on dealing with compound propositions made up of simple propositions joined by logical connectors like "and", "or", and ...

His lasting theory, Boolean logic, is a form of algebra where all the values (or variables) are either "true" or "false".

But in Boolean Algebra, the values of variables are true and false, and the operations are logical. There are three fundamental operations in Boolean Algebra: a NOT, an AND, and an OR operation.

This work built on the Boolean algebra developed by George Boole and an analysis of logic by Augustus De Morgan which these mathematicians published nearly simultaneously in 1847.

Excel Boolean logic: How to sift spreadsheet data using AND, OR, NOT, and XOR Excel logical functions make it easy to find the data you want, especially in huge spreadsheets.

1815: English mathematician George Boole, who would help establish what is now known as Boolean logic, is born. Boole’s breakthrough was the insight that logic, which had previously been ...
