How to Write the Logical NOT Symbol (¬) in LaTeX

In LaTeX, you can write the logical NOT symbol (¬) using the \neg command.

The following examples show how to write the logical NOT symbol in LaTeX.

How to Write the Logical NOT Symbol in Text

We can use the \neg command to write the logical NOT symbol in LaTeX document for text.

Suppose we want to write the logical NOT 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 logical NOT symbol \(\neg\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the logical NOT symbol ¬ in a sentence.

In this example, we use the \neg command to display the logical NOT symbol in the text.

How to Write the Logical NOT Symbol in Mathematical Expressions

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

Suppose we would like to write mathematical expressions that contain the logical NOT symbol.

We can use the following LaTeX code to do so:

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

An inline mathematical expression: \( \neg P \).

A displayed mathematical expression:
\[
\neg P \implies Q
\]

\end{document}

Output: 👇️

Logical NOT Symbol

In this example, we use the \neg command to denote the logical NOT symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \neg command for both text and mathematical expressions. This ensures that the logical NOT symbol is properly formatted and displayed in your LaTeX document.
