# editing the counting of section

I've found this .cls template on the web and modified it a little bit (I deleted the title page part, otherwise my post would be to long):

The problem is the following: The numbering of the theorem is like this: 1.0.3, where 1 (chapter). 0 (section) 3.(the number of the object in this section). I would like to modify the .cls template in such a way, that section starts counting at 1 instead of 0. How could I fix this, which means what do I have to change in this template? Thanks for your help

The section counter is incremented by the \section command. If you increment the counter manualy with \stepcounter{section} before the first section header then you first section will be numberd 2. The answer is to put a section header before your first theorem. The zero you see is correct because there are no section header yet, – Danie Els Apr 25 '12 at 10:50
It would be helpful if you augmented your posting with a MWE that generates the unwanted behavior. From your description alone, it would appear that you have a \chapter statement and later a \subsubsection statement, but no intermediate \subsection statement. If that's the case, there's nothing wrong with the class file you're working with. – Mico Apr 25 '12 at 10:53
Thanks you both for your comments. Sorry if my questions was not that clear. My first chapter is the Introduction. There I do not want to subdivide it into different sections. But I also want that a Theorem is stated like: Theorem 1.1.1 instead of Theorem 1.0.1 – math Apr 25 '12 at 11:02
So you just need to put \stepcounter{section} immediately after \chapter{Introduction}, and likewise for any other chapters that are not divided into sections. It's a bit odd to have theorems in the introduction, though! – Ian Thompson Apr 25 '12 at 12:06
perfect, that's exactly what I wanted! – math Apr 25 '12 at 12:52

If you are using a theorem number of 1.1.1, 1.1.2, etc in a chapter without sections it can be very confusing. I recommend that you reset the theorem counter to a lower level for such chapter, e.g. 1.1, 1.2, etc.

I cannot see where the theorem definition is but assume it is with the amsthm package. See code below

Edit 1: Move \setthmtochp and \setthmtosec before \chapter commands

\documentclass{report}
\usepackage{amsmath,amsthm}
\usepackage{remreset}

\newtheorem{thm}{Theorem}[section]
\renewcommand\thethm{\thesection.\arabic{thm}}

\makeatletter
\newcommand\setthmtochp{%
\@removefromreset{thm}{chapter}% just in case ... (no harm done)
\@removefromreset{thm}{section}%
\renewcommand\thethm{\thechapter.\arabic{thm}}}
\newcommand\setthmtosec{%
\@removefromreset{thm}{chapter}%
\@removefromreset{thm}{section}% just in case ... (no harm done)
\renewcommand\thethm{\thesection.\arabic{thm}}}
\makeatother

\begin{document}
\setthmtochp%--Edit 1
\chapter{Introduction}
\begin{thm}[The title]Some statements ... \end{thm}
\begin{thm}[The title]Some statements ... \end{thm}

\setthmtosec%--Edit 1
\chapter{First Chapter}
\section{A section}
\begin{thm}[The title]Some statements ... \end{thm}
\begin{thm}[The title]Some statements ... \end{thm}

\section{A section}
\begin{thm}[The title]Some statements ... \end{thm}
\begin{thm}[The title]Some statements ... \end{thm}
\end{document}


I see that \@removefromreset is already defined in your class and you may not need the remreset package.

 Thanks! that's even better! – math Apr 25 '12 at 13:33 @math: Please see changes where \setthmtochp and \setthmtosec` was moved to be before \chapter commands – Danie Els Apr 25 '12 at 13:49
