Summary
Calculate set operations on two user-defined sets. Enter comma-separated values for Set A and Set B to get union (A∪B), intersection (A∩B), difference (A−B and B−A), and symmetric difference (A△B).
How it works
- Enter comma-separated values for Set A (e.g. 1, 2, 3, apple).
- Enter comma-separated values for Set B (e.g. 2, 3, 4, banana).
- Click Calculate to see all four set operations instantly.
- Results show the element list and count for each operation.
- Duplicate values within a set are automatically removed.
Use cases
- Verify set theory homework answers quickly.
- Find common elements between two data lists.
- Identify items in one list that are missing from another.
- Explore Venn diagram relationships for presentations or analysis.
