Learn what is **union of sets**? And learn how to find out the **union** for the given sets. This topic is very important in the set theory chapter and easy also. So before moving to our main concept first we will learn what is a set and also basic things about it.

*What is the meaning of a set*? A set is nothing but collection of some distinct things/objects. Objects in the set are called as “elements of a set”. Elements of a set are generally represented by the small letters. While a set is always represented with the capital letter only. Now let’s go to the topic **union of sets**. With an example I will try to explain it clearly. So go through the below example and learn how to find **union of sets**.

**Procedure to find union of sets: **

Let us consider any two sets (not only two any number of sets we can take). Here am considering the two sets P and Q. sets P and Q elements are given below.

P ={ 1, 3, 5, 10, 14, 17, 23, 27, 29, 30, 31, 42}

Q = { 5, 10, 11, 23, 25, 28, 30, 33, 39, 45, 49, 54}

**P union Q **is a set which contains all the elements of either P or either Q or both sets P and Q. P union Q is denoted by P ∪ Q, “∪ ” -this symbol stands for union.

Therefore,

P ∪ Q = { 1, 3, 5, 10, 11, 14, 17, 23, 25, 27, 28, 29, 30, 31, 33, 39, 42, 45, 49, 54}

It is clear that the **union of the sets** P and Q have the elements of both the sets P and Q. I hope you understood how to find the union of sets. Any doubts let me know.
