+Predicate Logic, also known as first-order logic, is a formal language for expressing intricate statements about objects, their attributes, and relationships. It expands upon [Propositional Logic](/wiki/Propositional_Logic) by introducing quantifiers, enabling assertions about "all" or "some" entities. This foundational system is vital for [Mathematics](/wiki/Mathematics) and theoretical computing.
