### What is Meant by Union of Sets?

In maths, sets are an organized collection of objects and can be represented in set-builder form or roster form. Usually, sets are represented in curly braces {}, for example, A = {1, 2, 3, 4, 5} is a set. A set is represented by a capital letter. The number of elements in the finite set is known as the cardinal number of a set. Various set operations can be defined such as union, intersection, difference of sets. The symbol represents the union is “U”. Let us take an example to understand it clearly.

**Example: **

If A = {1, 2, 3} and B = {5, 6}, then find A U B.

**Solution:**

Given,

A = {1, 2, 3}

B = {5, 6}

A U B = {1, 2, 3} U {5, 6}

= {1, 2, 3, 5, 6}
