    In mathematical logic the predicate calculus, predicate logic or calculus of propositional functions is a formal system used to describe mathematical theories.

    The predicate calculus is an extension of propositional calculus, which is inadequate for describing more complex mathematical structures. Grammatically speaking the predicate calculus adds a predicate-subject structure and quantifiers on top of the existing propositional calculus. A subject is a name for a member of a given group of individuals (a set) and a predicate is a relation on this group.

    The propositional logic is not powerful enough to represent all types of assertions that are used in computer science and mathematics, or to express certain types of relationship between propositions such as equivalence.

    Thus we need more powerful logic to deal with these and other problems. The predicate logic is one of such logic and it addresses these issues among others
