I need to override the default equation numbering behavior.

I want the numbers next to equations in my Beamer slide presentation to match with the numbers of the same equations in my paper.

so instead of equations 1,2,3,4,...

it would be equations 2.2, 5.1, 7.1, 7.2 ...

Beamer loads the amsmath package, so you can just use the \tag command to supply the specific number for each equation:

\begin{equation}
\tag{2.2}
y = x^{2}
\end{equation}

@Munn thank you ! – b_dev Feb 22 '11 at 17:58

Simply redefining \theequation to 2.2, 5.1, 7.1, 7.2, ..., direct before the equation should do the trick. You can do this using:

\renewcommand*{\theequation}{2.2}

If you have issues with that try:

\gdef\theequation{2.2}
