How to Write the Left Implication Symbol (⇐) in LaTeX

In LaTeX, you can write the left implication symbol (⇐) using the \Leftarrow command.

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

How to Write the Left Implication Symbol in Text

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

Suppose we want to write the left implication 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 left implication symbol \( B \Leftarrow A \) in a sentence.

\end{document}

Output: 👇️

This is an example of using the left implication symbol B ⇐ A in a sentence.

In this example, we use the \Leftarrow command to display the left implication symbol in the text.

How to Write the Left Implication 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 left implication symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( B \Leftarrow A \).

A displayed mathematical expression:
\[
B \Leftarrow A
\]

\end{document}

Output: 👇️

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

Conclusion

We can use the \Leftarrow command for both text and mathematical expressions. This ensures that the left implication symbol is properly formatted and displayed in your LaTeX document.
