I would like to number equations (in increasing order using positive integers) so that the number appears in parenthses (n) in the right margin. Currently, my equation numbers appear in the left margin and the number corresponding to the nth equation in section m is (m.n). How can I edit the numbers and the location?

MWE

\documentclass[english]{amsart}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{amsthm}
\usepackage{setspace}

\makeatletter
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands.
\numberwithin{equation}{section}
\numberwithin{figure}{section}

\makeatother

\usepackage{babel}
\begin{document}

\section{\textbf{Introduction.}}

\begin{doublespace}
\begin{equation}
A=B
\end{equation}
\end{doublespace}

\end{document}

  • If you want the equation numbers be simple integers that are incremented consecutively, get rid of the \numberwithin{equation}{section} statement. – Mico Nov 25 '15 at 06:46

  • @Werner, Indeed. I had no idea that was in my selection box. Must be a default. – The Substitute Nov 25 '15 at 07:04
  • Yes. If you find the marked question not a duplicate, then you can view to reopen and I can write a complete answer. – Werner Nov 25 '15 at 07:06

To have the numbering on the right, you have to replace \documentclass[english]{amsart} by \documentclass[english,reqno]{amsart} (See Placing equation numbers on the right)

Edit : and like @Mico said, juste comment your numberwithin commands

  • I am using LyX and don't know how to replace \documentclass[english]{amsart}. When I include \documentclass[english,reqno]{amsart} into my source code LyX says there's a error ("the document may only declare one class"). – The Substitute Nov 25 '15 at 06:56
  • Nevermind. Werner's comment resolves the issue. – The Substitute Nov 25 '15 at 07:02
