Propositional logic is also known as sentential logic, statement logic, and propositional calculus. It is a branch of logic that deals with propositions or statements that are either true or false. Propositional logic is used as a tool to analyze arguments, particularly in the fields of mathematics, computer science, and philosophy. Some other terms often used to refer to propositional logic include Boolean logic, which refers to the algebraic structures that underlie propositional logic, and symbolic logic, which emphasizes the manipulation of symbols rather than the meaning of propositions. Regardless of the term used, propositional logic remains a fundamental part of logical reasoning and continues to be studied by scholars worldwide.
