# How to Write the Intersection Symbol (∩) in LaTeX

In LaTeX, you can write the intersection symbol (∩) using the `\cap`

command.

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

## How to Write the Intersection Symbol in Text

We can use the `\cap`

command to write the intersection symbol in LaTeX document for text.

Suppose we want to write the intersection symbol in the text.

We can use the following LaTeX code to do so:

```
\documentclass{article}
\begin{document}
This is an example of using the intersection symbol \( A \cap B \) in a sentence.
\end{document}
```

Output: 👇️

```
This is an example of using the intersection symbol A ∩ B in a sentence.
```

In this example, we use the `\cap`

command to display the intersection symbol in the text.

## How to Write the Intersection Symbol in Mathematical Expressions

For mathematical expressions, We can use the `\cap`

command to ensure proper formatting.

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

We can use the following LaTeX code to do so:

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

Output: 👇️

In this example, we use the `\cap`

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

## Conclusion

We can use the `\cap`

command for both text and mathematical expressions. This ensures that the intersection symbol is properly formatted and displayed in LaTeX document.
