# How do I label equations without the chapter number? [duplicate]

I have an equation, such as:

\documentclass{report}

\begin{document}

\chapter{hello}
$$x=1$$
\end{document}


And the equation appears as "x=1 (1.1)".

What I want is "x=1 (1)" ignoring the chapter number. How do I get that?

Thank you.

You can use the package chngcntr
\documentclass{report}
$$x=1$$
