Set Operations and Venn Diagrams
📘 Overview Set operations construct sets by combining or excluding elements according to membership rules. A Venn diagram represents sets as overlapping regions inside a universal set ; shading identifies the elements included in an operation's result.
🧠 Key Idea An element belongs to a resulting set exactly when it satisfies the operation's membership condition. Union, intersection, and complement correspond to the Boolean operations OR, AND, and NOT.
