\newtheorem{theorem}{Theorem}[section]
\begin{document}
\subsection*{1}
\begin{theorem}
blah is blah
\end{theorem}
\begin{theorem}
bloo is bloo
\end{theorem}
\subsection*{2}
\begin{theorem}
bleh is bleh
\end{theorem}
\begin{theorem}
blih is blih
\end{theorem}
\end{document}
This shows up as:
1.
Theorem 0.1. blah is blah
Theorem 0.2. bloo is bloo
2.
Theorem 0.3. bleh is bleh
Theorem 0.4. blih is blih
How can I reset the counter so that in my second un-numbered subsection, Theorem 0.3 is reset to Theorem 0.1 (and also make Theorem 0.4 as Theorem 0.2)?
(I put un-numbered subsections because for this particular documentclass, the sections are centered which I don't like, so I start off by using subsections, but the subsection numbering starts with 0.1, and I want it to start with 1. so I un-numbered the subsections and put in my own numbers.)
