Finally, I can help instead of getting helped! I had the exact same problem
just recently. Add to the LaTeX preamble the following line, if you are
using the article class:
\renewcommand{\theequation}{\thesection.\arabic{equation}}
This works for figues and tables also:
\renewcommand{\thefigure}{\thesection.\arabic{figure}}
\renewcommand{\thetable}{\thesection.\arabic{table}}
The AMS article class does this automatically, but it seems to have
problems with fancy headers and footers. (or perhaps I did something wrong,
which is a good possiblity!)

Try:
\addtocounter{equation}{-1}

Same here! But it solved the massive problems I was having using Word. If it
wasn't the most used format, I'd drop it completely. Unfortuneatly,
translating LaTeX to Word is a tedious problem if you're doing more than
just simple documents.
