Set Theory Calculator Set A (comma-separated elements): Set B (comma-separated elements): Universal Set U (comma-separated, required for Complement): ? The Universal Set (U) contains all possible elements under consideration. It's needed to calculate the complement (elements NOT in a set). A ∪ B (Union) A ∩ B (Intersection) A \ B (Difference) B \ A (Difference) A Δ B (Symmetric Diff.) |A| (Cardinality) |B| (Cardinality) A ⊆ B? (Subset) B ⊆ A? (Subset) A = B? (Equality) A' (Complement) B' (Complement) Results will appear here... Clear All Download Results as PDF
