We need to decide how names and predicates will be combined. Different methods have been used, but most common is what is called “prefix notation”. This means we put the predicate before names. So, if we had the sentences

WebWe use a recursion scheme for the formulas of first-order predicate logic. These are like propositional logic formulas, except: An atomic proposition is a predicate: a string constant accompanied by a list of terms. Subformulas may be quantified by a universal (Forall) or existential (Exists) quantifier.
