How to Write the Double Left Arrow Symbol (⇐) in LaTeX

In LaTeX, you can write the double left arrow symbol (⇐) using the \Leftarrow command. This command is part of the amsmath package, so you need to include this package in your LaTeX document.

The following examples show how to write the double left arrow symbol in LaTeX.

How to Write the Double Left Arrow Symbol in Text

We can use the \Leftarrow command to write the double left arrow symbol in LaTeX document for text.

Suppose we want to write the double left arrow symbol in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amsmath}
\begin{document}

This is an example of using the double left arrow symbol: \( \Leftarrow \).

\end{document}

Output: 👇️

This is an example of using the double left arrow symbol: ⇐.

In this example, we use the \Leftarrow command to display the double left arrow symbol in the document.

How to Write the Double Left Arrow Symbol in Mathematical Expressions

For mathematical expressions, we can use the \Leftarrow command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the double left arrow symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amsmath}
\begin{document}

An inline mathematical expression: \( a \Leftarrow b \).

A displayed mathematical expression:
\[
a \Leftarrow b
\]

\end{document}

Output: 👇️

a ⇐ b

In this example, we use the \Leftarrow command to denote the double left arrow symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \Leftarrow command from the amsmath package for both text and mathematical expressions.
