I am having trouble numbering chapters, equations, and sections in a coherent way in the amsbook class. I would like sections to be numbered according to chapters, e.g.

Chapter 1

Section 1.1

Subsection 1.1.1

equation 1.1

equation 1.2

equation 1.3....


Chapter 2

Section 2.1

Subsection 2.1.1

equation 2.1..

Right now I am using the preamble




and this numbers equations coherently within chapters, but not subsections. I can't figure out how to change it. If anyone has any comments (or suggestions on a better alternative) it would be much appreciated.

Thanks a lot.

You don't want to remove the section counter from the reset list of chapter.


% remove equation from the reset list of section
% add equation to the reset list of chapter


\chapter{Chapter 1}

\section{Section 1.1}

\subsection{Subsection 1.1.1}

equation 1.1\\
equation 1.2\\
equation 1.3

\section{Section 1.2}

equation 1.4\\
equation 1.5\\
equation 1.6

\chapter{Chapter 2}

\section{Section 2.1}

\subsection{Subsection 2.1.1}

equation 2.1


The * forms of \counterwithin and \counterwithout don't change the representation of the counter they act on.
