How to Write the Not Element Of Symbol (∉) in LaTeX

In LaTeX, you can write the not element of symbol (∉) using the \notin command.

The following examples show how to write the not element of symbol in LaTeX.

How to Write the Not Element Of Symbol in Text

We can use the \notin command to write the not element of symbol in LaTeX document for text.

Suppose we want to write the not element of 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 not element of symbol \( a \notin A \) in a sentence.

\end{document}

Output: 👇️

This is an example of using the not element of symbol a ∉ A in a sentence.

In this example, we use the \notin command to display the not element of symbol in the text.

How to Write the Not Element Of Symbol in Mathematical Expressions

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

Suppose we would like to write mathematical expressions that contain the not element of symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( a \notin A \).

A displayed mathematical expression:
\[
a \notin A
\]

\end{document}

Output: 👇️

In this example, we use the \notin command to denote the not element of symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \notin command for both text and mathematical expressions. This ensures that the not element of symbol is properly formatted and displayed in your LaTeX document.
