## What does “for all (∀) symbol” mean in mathematics?

In mathematics, the symbol “∀” represents the universal quantifier “for all” or “for every.” It expresses that a particular statement is true for every element in a given set or domain. The symbol is read as “for all” or “for every.”

\documentclass{article}

\begin{document}

Here is an example: Let $$P(x)$$ be the statement x is a positive integer." Then, $$\forall x \, P(x)$$ would be read as for all $$x$$, $$x$$ is a positive integer," indicating that every element $$x$$ in the set is a positive integer.

\end{document}
