There's not much to tell about TeX-Math.INF, which is intended to help people typesetting
mathematical formulae. More general advice is available in the first chapter
"Introduction." To view the file, enter "view tex-math" on any OS/2 shell.

Or create a book in your "Information" folder on your desktop using the following
procedure:
a) Drag a "program" template from the "Templates" folder into the "Information" folder.
b) Enter "view.exe" in the "Path and file name:" box and
   the full path and file name of the TeX-Math.INF file in the "Parameter:" box.
c) Select the "General" tab and enter any title you like, e.g. "Math with LaTeX"
d) Close the "Settings" notebook.
e) Start with reading the "Introduction" chapter.
