Set Operations Calculator
Set theory is one of the fundamental concepts in mathematics, computer science, statistics, and logic. Sets help organize and analyze collections of objects, numbers, symbols, or data elements. When working with multiple sets, performing operations manually can become time-consuming and may lead to calculation mistakes.
The Set Operations Calculator is a simple and effective tool that helps users quickly perform important set calculations between two sets. It can calculate union (A ∪ B), intersection (A ∩ B), difference (A – B), difference (B – A), and symmetric difference (A Δ B) within seconds.
This calculator is useful for students, teachers, researchers, programmers, and anyone learning or applying set theory. By entering the elements of Set A and Set B, users can instantly view the operation result and the total number of elements in the resulting set.
Whether you are solving mathematics problems, studying probability, analyzing data, or learning programming concepts, this Set Operations Calculator makes set calculations faster and easier.
What Is a Set?
A set is a collection of distinct objects or elements grouped together according to a specific definition or condition. The elements inside a set can be numbers, letters, words, symbols, or other objects.
Sets are usually represented using curly brackets { }.
For example:
Set A = {1, 2, 3, 4, 5}
In this example:
- The set name is A.
- The elements are 1, 2, 3, 4, and 5.
- Each value inside the brackets is called an element of the set.
Sets cannot contain duplicate values. For example:
{1, 2, 2, 3, 4}
is simplified as:
{1, 2, 3, 4}
because repeated elements are counted only once.
What Is a Set Operations Calculator?

Types of Set Operations Explained
1. Union of Sets (A ∪ B)
The union combines all elements from both sets without repeating duplicate values.
Formula:
A ∪ B = {x | x belongs to A or x belongs to B}
Example:
Set A:
{1, 2, 3, 4}
Set B:
{3, 4, 5, 6}
Union:
{1, 2, 3, 4, 5, 6}
The repeated values 3 and 4 appear only once.
2. Intersection of Sets (A ∩ B)
The intersection contains only elements that exist in both sets.
Formula:
A ∩ B = {x | x belongs to A and x belongs to B}
Example:
Set A:
{1, 2, 3, 4}
Set B:
{3, 4, 5, 6}
Intersection:
{3, 4}
Only common elements remain.
3. Difference of Sets (A – B)
The difference operation finds elements that exist in Set A but not in Set B.
Formula:
A – B = {x | x belongs to A and x does not belong to B}
Example:
Set A:
{1, 2, 3, 4}
Set B:
{3, 4, 5, 6}
A – B:
{1, 2}
Elements 3 and 4 are removed because they are also present in Set B.
4. Difference of Sets (B – A)
This operation finds elements present in Set B but not in Set A.
Formula:
B – A = {x | x belongs to B and x does not belong to A}
Example:
Set A:
{1, 2, 3, 4}
Set B:
{3, 4, 5, 6}
B – A:
{5, 6}
5. Symmetric Difference (A Δ B)
Symmetric difference contains elements that exist in either set but not in both.
Formula:
A Δ B = (A – B) ∪ (B – A)
Example:
Set A:
{1, 2, 3, 4}
Set B:
{3, 4, 5, 6}
Symmetric Difference:
{1, 2, 5, 6}
Common elements 3 and 4 are excluded.
