How to Write the Multiset Union Symbol (⊎) in LaTeX

In LaTeX, you can write the multiset union symbol (⊎) using the \uplus command.

The following examples show how to write the multiset union symbol in LaTeX.

How to Write the Multiset Union Symbol in Text

We can use the \uplus command to write the multiset union symbol in LaTeX document for text.

Suppose we want to write the multiset union 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 multiset union symbol \(A \uplus B\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the multiset union symbol A ⊎ B in a sentence.

In this example, we use the \uplus command to display the multiset union symbol in the text.

How to Write the Multiset Union Symbol in Mathematical Expressions

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

Suppose we would like to write mathematical expressions that contain the multiset union symbol.

We can use the following LaTeX code to do so:

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

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

A displayed mathematical expression:
\[
A \uplus B = \{ x \mid x \in A \text{ or } x \in B \}
\]

\end{document}

Output: 👇️

In this example, we use the \uplus command to denote the multiset union symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \uplus command for both text and mathematical expressions. This ensures that the multiset union symbol is properly formatted and displayed in LaTeX document.
