How to Write the Down Arrow Symbol (↓) in LaTeX

In LaTeX, you can write the down arrow symbol (↓) using the \downarrow command.

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

How to Write the Down Arrow Symbol in Text

We can use the \downarrow command to write the down arrow symbol in LaTeX document for text.

Suppose we want to write the down arrow symbol in the text.

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

\end{document}

a ↓ b

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

Conclusion

We can use the \downarrow command for both text and mathematical expressions.
