Predicate Calculus
Predicate calculus, also known as first-order logic, is a formal system used to represent and reason about facts and relationships in a precise way. It extends propositional logic by incorporating predicates, which express properties or relationships between objects, and quantifiers, such as "for all" or "there exists." This enables us to formulate statements like "All humans are mortal" or "Some animals are mammals." Predicate calculus allows for rigorous reasoning in mathematics, computer science, and philosophical logic, helping us deduce new information based on established facts and draw valid conclusions from complex statements.
