Discrete Mathematics | Lec-4 | Predicates | Universal, Existential & Uniqueness Quantifiers

Welcome to Lecture 4 of our Discrete Mathematics series!
In this lecture, we explore predicates and the different types of quantifiers used in mathematical logic, including universal, existential, and uniqueness quantifiers, with detailed examples.

📚 Topics Covered in This Lecture:

Introduction to predicates and predicate logic

Universal quantifier (∀) – meaning and usage

Existential quantifier (∃) – meaning and usage

Uniqueness quantifier (∃!) – definition and applications

Examples and step-by-step explanations
