The simple pause works in beamer. The following code under beamer class will do the job:
\begin{frame}\frametitle{uncover incrementally }$ a=0$see this \pause and then that \pause\begin{equation}   a=\pause b+ \pause c\end{equation}\end{frame} 
If you want to color your math red, put this in the preamble:
\setbeamercolor{math text}{fg=red}  
It is possible to use  different colors for inline and displayed math.
To make the color of the background reddish at the bottom and yellowish at the top, add this before the frame:
\setbeamertemplate{background canvas}[vertical shading][bottom=red!20,top=yellow!30]
I find beamer very versatile.
