How to not number an equation?

Question

I use lualatex with the package unicode-math instead of amsmath. How can I insert an equation without numbering? \nonumber option doesn't work with unicode-math package, and \begin{equation*} either.

Welcome to TeX.SX! Please help us (and also you) and add a minimal working example (MWE), that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass and ending with \end{document}. — Bobyandbob, Jun 04 '17 at 11:27
There is not reason not to use amsmath together with unicode-math (but load amsmath first). — Ulrike Fischer, Jun 04 '17 at 11:53
unicode-math is not a substitute for amsmath. The latter is not related in any way with math font selection. For technical reasons, it should be loaded before unicode-math. — egreg, Jun 04 '17 at 14:15
Thanks, i solved it. The problem was that the amsmath package produced error and I thought it was incompatible with unicode-math. I introduced it in the first place and it already works for me. — eissen, Jun 04 '17 at 18:15
If someone come across this searching for the title, refer to How do I turn off equation auto numbering - TeX - LaTeX Stack Exchange (align → align*). — user202729, May 31 '23 at 13:13

This works for me with LuaLaTeX:

\documentclass{memoir}
\usepackage{amsmath}
\usepackage{unicode-math}
\usepackage[noabbrev]{cleveref}

\begin{document}

\begin{align*}
    A
        &=B         \\
        &=BCD       \\
        &=B         
\end{align*}

\begin{align}
    A
        &=B         \label{eq:1}\\
        &=B         \notag\\
    A
        &=BCD       \label{eq:2}\\
        &=B         \label{eq:3}\tag{foo}
\end{align}

References: \eqref{eq:1}, \cref{eq:2}, \cref{eq:2,eq:1}, \cref{eq:2,eq:1,eq:3}.

\end{document}

As far as I know \notag and \nonumber are synonyms.

The OP wants NO numbers... – TeXnician Jun 04 '17 at 12:41

Use the starred equation*:

\documentclass[11pt,a4paper]{article}
\usepackage{amsmath,esint}
\begin{document}
    \begin{equation}
        E=mc^2
    \end{equation}
\end{document}
