Technical Definition

A formal system that uses quantified variables and predicates to express logical propositions about objects and their properties.

How it works

Predicate logic, also known as first-order logic, is a formal system used extensively in mathematics, philosophy, and computer science. It extends propositional logic by allowing the use of variables, predicates, and quantifiers (like 'for all' and 'there exists') to represent more complex statements.
