Predicate logic and propositional logic are both formal systems used in logic and mathematics to represent and analyze the relationships between propositions, but they have distinct characteristics and purposes.

Propositional Logic: Propositional logic deals with propositions as atomic units, without considering their internal structure. It uses logical connectives such as AND (∧), OR (∨), NOT (¬), IMPLIES (→), and IF AND ONLY IF (↔) to create compound propositions. However, it lacks the ability to express the internal properties of statements.
