How to Find Complement, Union, Intersection, and Difference — Step-by-Step Decision Flowchart

How to Find Complement, Union, Intersection, and Difference — Step-by-Step Decision Flowchart

The map in words

  • Start: Set Operation Problem
    • Which operation?
      • Complement A prime: Identify Universal Set U
        • List elements in U but NOT in A
          • Result is A prime = U minus A
            • Remember: U must be specified for complement
      • Union A union B: List ALL elements of A
        • Add elements of B not already listed
          • Result is A union B
            • Common elements counted ONCE only
      • Intersection A inter B: Find elements in BOTH A and B
        • Result is A inter B
      • Difference A minus B: Start with elements of A
        • Remove elements that are also in B
          • Result is A minus B
            • A minus B is NOT equal to B minus A
