# How to Write Curly Braces {} in LaTeX

In LaTeX, curly braces `{}`

are used for grouping and have special meanings. To display curly braces as characters, you need to escape them using a backslash `\`

.

The following examples show how to write curly braces in LaTeX.

## How to Write Curly Braces in Text

We can directly use curly braces in a LaTeX document for text by escaping them with a backslash.

### Example: Curly Braces in Text

Suppose we want to write curly braces in the text.

We can use the following LaTeX code to do so:

```
\documentclass{article}
\begin{document}
This is an example of using curly braces \{like this\} in a sentence.
\end{document}
```

Output: 👇️

```
This is an example of using curly braces {like this} in a sentence.
```

In this example, we use the curly braces to enclose a part of the sentence.

## How to Write Curly Braces in Mathematical Expressions

In mathematical expressions, we can also use the backslash `\`

to escape curly braces.

### Example: Curly Braces in Mathematical Expressions

Suppose we would like to write mathematical expressions that contain curly braces.

We can use the following LaTeX code to do so:

```
\documentclass{article}
\begin{document}
An inline mathematical expression: \( \{a, b, c\} \).
A displayed mathematical expression:
\[
\left\{ \frac{a}{b}, \frac{c}{d} \right\}
\]
\end{document}
```

Output: 👇️

In this example, we use the curly braces are used to enclose elements in a set. The `\left\{`

and `\right\}`

commands are used to adjust the size of the curly braces to fit the enclosed fractions.

## Conclusion

Using curly braces in LaTeX requires escaping them with a backslash `\`

. This allows us to display curly braces as characters in both text and mathematical expressions.

For larger expressions, the `\left\{`

and `\right\}`

commands help in adjusting the size of the curly braces automatically.
