# What are the Sets?

## Definition of a Set

In mathematics and logic, a Set is an unorderly collection of objects or elements which may be mathematical or non-mathematical. A Set can be formed by any kind of objects like people, animals, letters, numbers, books, lines, or even other sets.

## Examples of Sets

Let, $A$ is a set of colours and $B$ is a set of numbers. Then, set $A$ and set $B$ can be written as:

$A = \{blue, white, red, green\}$

$B = \{1, 2, 3, 4, 5, 6\}$

The list of elements in a set is written within curly brackets ‘$\{\}$’.

The objects inside a set are called elements. For example, $‘blue’, ‘white’, ‘red’, ‘green’$ are the elements of set $A$.

Similarly, $‘1’, ‘2’, ‘3’, ‘4’, ‘5’$ and $‘6’$ are the elements of set $B$.
