The representation of similar types of data is called the set. Union of a set is the basic operation on the sets which is used to find all the entries of the given sets. It is one of the operators on the set which is used to solve the set theory problems. Union of two sets means finding a set that contains all the values in both the given sets. It is denoted using the symbol ‘∪’ and is read as the union, i.e.
If A = {1,3.5.7} and B = {2,4,6,8} then A∪B is read as A union B and its value is,
A∪B = {1,2,3,4,5,6,7,8}

The union of any two or more sets is a set that contains all the elements of the previous sets. The union of two setsis equivalent to the logical operation OR and it means any of the given values, for example, if we take a set A = {a, e, i, o, u} and set B = {a, b, c, d, e} then OR operations signifies any of the value of … See more
We can easily find the union of two sets by taking all the elements of both sets and removing the common elements. Let’s learn this concept through an example. Example: Find the union of the sets, set A = {p, q, r, s, t, u} and set B = {s, t, u, v, w,}. Solution: See more
Union of the sets is represented using the symbol “∪”. It is placed between two sets whose union is to be found. We read this symbol as “union”. Example A∪B is read as A union B, furthermore we can also find the union of two or more sets as the union of set A, set B, and … See more

Union (set theory) - Wikipedia
In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero ($${\displaystyle 0}$$) sets and it is by definition equal to the empty set.
