# How to Write the Empty Set Symbol (∅) in LaTeX

In LaTeX, you can write the empty set symbol (∅) using the `\emptyset`

command. This command is part of the `amssymb`

package, so you need to include this package in your LaTeX document.

The following examples show how to write the empty set symbol in LaTeX.

## How to Write the Empty Set Symbol in Text

We can use the `\emptyset`

command to write the empty set symbol in LaTeX document for text.

Suppose we want to write the empty set symbol in the text.

We can use the following LaTeX code to do so:

```
\documentclass{article}
\usepackage{amssymb}
\begin{document}
This is an example of using the empty set symbol \( \emptyset \) in a sentence.
\end{document}
```

Output: 👇️

```
This is an example of using the empty set symbol ∅ in a sentence.
```

In this example, we use the `\emptyset`

command to display the empty set symbol in the text.

## How to Write the Empty Set Symbol in Mathematical Expressions

For mathematical expressions, we can use the `\emptyset`

command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the empty set symbol.

We can use the following LaTeX code to do so:

```
\documentclass{article}
\usepackage{amssymb}
\begin{document}
An inline mathematical expression: \( \emptyset \).
A displayed mathematical expression:
\[
\emptyset
\]
\end{document}
```

Output: 👇️

In this example, we use the `\emptyset`

command to denote the empty set symbol in both inline and displayed mathematical expressions.

## Conclusion

We can use the `\emptyset`

command from the `amssymb`

package for both text and mathematical expressions. This ensures that the empty set symbol is properly formatted and displayed in your LaTeX document.
