Algebra 04 - Complement and Relative Complement

Professor Von Schmeelk introduces the concept of set complements and relative complements using Venn diagrams. The lecture explains the definition of a set's complement, emphasizing the importance of defining a universal set. Examples are provided using integers and natural numbers. The lecture also covers the concept of relative complements, highlighting the differences from absolute complements. The session concludes with a preview of the next lecture on symmetric difference.
