Set Calculator

How to Use

Enter your set elements separated by commas, like this: 1, 2, 3, 4 or a, b, c.

Then pick an option to find:

Union (A ∪ B): All elements that are in Set A or Set B (or both)
Intersection (A ∩ B): Only the elements that are in both Set A and Set B
Difference (A − B): Elements that are in Set A, but not in Set B

Note: Sets don't care about order, and don't have duplicate elements. If you type duplicates, the calculator will automatically simplify them to a single element!
