Math & Science ⇒ babel and amsmath

[Hamed]

Hi,
When I latexed the example below I did not get "X" in the outcome of the file. Is there a solution for this?
Thanks a lot for the help.

Code: Select all

\documentclass{article}
\usepackage{amsmath,bm}
\usepackage[cp1256]{inputenc}
\usepackage[arabic,english]{babel} 
\begin{document} 

$\frac{d}{dt}[\bm{r}(t)\times\bm{s}(t)]=\bm{r}'(t)\times\bm{s}(t)+\bm{r}(t)\times\bm{s}'(t)$

\end{document}

Hi Hamed,

you could store \times in your own macro and restore it after loading babel:

Code: Select all

\let\oldtimes\times
\usepackage[arabic,english]{babel}
\let\times\oldtimes
