Expert Solution

Step 1

Introduction

Predicate Logic:

In mathematics and computer science, predicate logic is a formal system of logic that is used to represent object attributes and relationships. By incorporating quantifiers into the language, such as "for all" () and "there exists" (), it expands propositional logic by enabling claims about predicates (relations) as well as the objects they apply to. Predicate logic is a vital tool for automated theorem proving and other applications because it offers a more expressive and adaptable means of reasoning about the relationships between objects and their attributes.
