Set Operations — Union, Intersection & Difference
Union, intersection, difference, symmetric difference plus subset/superset checks. Duplicates removed automatically.
How to use
- 1 Enter the elements of set A and set B, separated by commas.
- 2 Union, intersection, differences and symmetric difference appear instantly.
- 3 Subset, superset and disjoint relationships are checked too.
Why use this tool
- All the common set operations and relations in one view.
- Duplicate elements are removed automatically.
- Runs entirely in your browser.
Frequently asked questions
What is the union of two sets?
A ∪ B contains every element that is in A, in B, or in both.
What is the intersection?
A ∩ B contains only the elements that are in both A and B.
What is the symmetric difference?
A △ B contains elements in exactly one of the sets — in A or B but not both.
What does “disjoint” mean?
Two sets are disjoint when they share no elements — their intersection is the empty set.
What is Set Operations Calculator?
