In LaTeX, you can write the “for all” symbol (∀) using the \forall command.

The following examples show how to write the “for all” symbol in LaTeX.

How to Write the “For All” Symbol in Text

We can use the \forall command to write the “for all” symbol in LaTeX document for text.

Suppose we want to write the “for all” symbol in the text.

We can use the following LaTeX code to do so:

\begin{document}

This is an example of using the "for all" symbol \(\forall\) in a sentence.

In this example, we use the \forall command to display the “for all” symbol in the text.

How to Write the “For All” Symbol in Mathematical Expressions

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

Suppose we would like to write mathematical expressions that contain the “for all” symbol.

We can use the following LaTeX code to do so:

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

An inline mathematical expression: \( \forall x \in A \).

A displayed mathematical expression:
\[
\forall x \in A \text{ such that } P(x)
\]

\end{document}

Output: 👇️

For All Symbol

In this example, we use the \forall command to denote the “for all” symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \forall command for both text and mathematical expressions. This ensures that the “for all” symbol is properly formatted and displayed in your LaTeX document.
