General ⇒ Putting boxes around an equation

[Noobix Cube]

How do you put a box around a numbered equation?

[localghost]

The amsmath package offers a simple box to matk equations.

Code: Select all

\begin{equation}\label{eqn:einstein}
  \boxed{E=mc^2}
\end{equation}

More capabilities are given with the empheq package from the mh bundle.
