In real number system, we can do four fundamental operation to form new number by combining or manipulating one or more existing numbers.

For example, given two numbers $2$ and $3$, we can use

Similarly, we can do Set operation to form new Set by combining or manipulating one or more existing Sets. Set operation helps to combine two or more sets together to form a new set. The common example of set operations are

Union, Intersection, Difference, and Complement.

##

Let $ A$ and $B$ be any two sets. Then union of sets $ A$ and $B$ is a new set consisting all the elements of $ A$ and $B$. It is denoted by $ A \cup B$ and read as “A union B”.

In Symbol, $ A \cup B = \{x: x \in A \text{ or } x\in B\}$.

For example, given two numbers $2$ and $3$, we can use

- $+$ to form a new number $5$ by $2+3$
- $\times$ to form a new number $6$ by $2 \times 3$

Similarly, we can do Set operation to form new Set by combining or manipulating one or more existing Sets. Set operation helps to combine two or more sets together to form a new set. The common example of set operations are

**Union of Sets**

In Symbol, $ A \cup B = \{x: x \in A \text{ or } x\in B\}$.
