Meaning and Definition

A formal system in mathematical logic for representing and manipulating statements (propositions) using logical connectives like AND, OR, NOT.

The branch of symbolic logic that deals with propositions as unanalyzed wholes, combining them with logical operators to determine truth values and derive valid inferences. It is the foundation of Boolean algebra and digital circuit design.

They are closely related and share the same underlying structure. Boolean algebra is the algebraic interpretation of propositional calculus, often applied in circuit design.

Typically: NOT (negation, ¬), AND (conjunction, ∧), OR (disjunction, ∨), IMPLIES (implication, →), and IFF (biconditional, ↔).

Its modern formalization is attributed to multiple logicians, including Gottlob Frege, Bertrand Russell, and Alfred North Whitehead in the late 19th and early 20th centuries.

A compound statement that is true for every possible assignment of truth values to its component propositions (e.g., 'P OR NOT P').
