In addition to Joseph's response, I propopse to use
\usepackage{amsmath} instead of \usepackage{amstex}.

Don't know why you used \documentstyle and tried to load amstex.sty.
Either you have some experience but didn't use LaTeX for much more
than a decade or you have an old book about an ancient version of
LaTeX.  If the latter is true, donate this book to a museum and use
online documentation instead.

Both, TeX Live and MiKTeX provide a command-line program called
texdoc.  If you type

  texdoc <macro package>

on the command line, you'll get the documentation of that macro
package.  Further documentation can be found here:

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
