# Placing equation numbers on the right

I am new to TeX and am using scribtex to write a maths paper. When I put the followng code, the equation number is automatically displayed on the left, instead of in the right as is usually done. What is the problem and how do I fix it? Thanks for your time.

 \documentclass[12pt,oneside]{amsart}
\usepackage{amssymb}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\begin{document}
Let us consider a spherical symmetric metric in curvature coordinates:
$$\label{metric} ds^2=-e^\lambda dr^2-r^2(d\theta^2+\sin^2\theta d\phi^2)+e^\nu dt^2$$
\end{document}​


The output I get is:

Add the reqno document class option to your current file:

\documentclass[12pt,oneside,reqno]{amsart}


This will override the default left equation numbering scheme of the amsart document class. The following, taken from the AMS document class documentation provides some background (p 7):

Equation numbering on the left or right

The option leqno - equation numbers on the left - is the default in AMS styles. Therefore we provide also a reqno option.

leqno and reqno are options of all document classes. I think your answer is too localized to amsart. –  Marco Daniel Oct 26 '11 at 11:31
@MarcoDaniel: I don't read the answer as implying that the leqno applies only to the amsart package; the answer was merely taking the OP's specific example and showed how to add the required option. –  Mico Oct 26 '11 at 12:04
@Mico: The answer is correct. My sentence based on the part default left equation numbering scheme of the amsart –  Marco Daniel Oct 26 '11 at 12:34
