This archive contains the shareware version of Mathomatic, the algebraic
manipulator.  A tutorial program is included.  This is an MS-DOS program, but
it will work under Windows.

This archive may be freely distributed as long as none of the files inside
are modified or missing.

The files that should be in the archive are:

  AC.BAT          Batch file for running Mathomatic in color mode.
  ADV.TXT         Advertisement and description of Mathomatic.
  AM.BAT          Batch file for running Mathomatic with no color.
  AMEDIT.BAT      File containing the name of the editor to use.
  AMTUTOR.EXE     The Mathomatic tutorial, demo, and program.
  AMTUTOR.ICO     A Mathomatic icon you can load under Windows.
  CHANGES         Version history of Mathomatic.
  FILE_ID.DIZ     Short description of Mathomatic.
  GRAPH.EXE       The Mathomatic Graph program (Requires EGA or VGA).
  HERON.IN        Read this into Mathomatic for the area of a triangle.
  LIMIT.IN        Read this into Mathomatic to learn how to do limits.
  ORDER.FRM       The Mathomatic registration form.
  POINTS.IN       Read this into Mathomatic to get equations from 2/3 points.
  README.TXT      This file.
  SMILE.IN        Something to graph.
  TORUS.IN        Equations for a torus.

To run the tutorial, type in "amtutor" at the DOS prompt.  If you have a
color computer and you have the "ANSI.SYS" driver loaded, you can see how
Mathomatic works in color by typing "amtutor -c" at the DOS prompt.  In color
mode, Mathomatic outputs ANSI escape sequences to make each level of
parentheses a different color.  To execute the shareware version of
Mathomatic, select it from the tutorial main menu or type "am" at the DOS
prompt (type "ac" for color mode).

If you are going to use color mode, you will need the following line to your
"\config.sys" file:

     device = \dos\ansi.sys

In color mode, Mathomatic changes the default text color on your screen to
green.  To run ANSI programs without changing the default text color, you
need to set the default color you want in your MS-DOS prompt.  The procedure
to do this is just one of many things described in the Mathomatic manual.

You must have at least 640K of memory in your computer to run Mathomatic.
Mathomatic runs on all IBM-PC and IBM-PC/AT compatibles with the MS-DOS
operating system.  The Mathomatic "graph" command requires EGA or VGA and
MS-DOS version 3.0 or higher.  A math coprocessor is recommended but not
required.

This shareware version of Mathomatic is fully functional, however the maximum
equation size has been reduced.

Mathomatic is written in Microsoft C V5.1, is self-testing, and strictly
follows the rules of algebra.  Mathomatic is powerful enough for users to
check their answers/solutions.



Registered users get the full-size version of Mathomatic with hardcopy
manual.  They also get my prime number tools and other math goodies.  The
full-size version allows equations three times larger than the shareware
version allows.  A 286 or higher processor is required for the registered
version.

To become a registered user, please do the following:

  1) Print the file "ORDER.FRM".  At the DOS prompt, type: PRINT ORDER.FRM
  2) Fill it out.
  3) Make out a check or money order payable to "George Gesslein II".
     It must be in U.S. dollars and drawn on a U.S. bank.
     A single user registration costs $49.95.
  4) Send the order form with check or money order to:

        George Gesslein II
        RD2 118 Sharpsteen Road
        Locke, New York  13092
        USA

FREE technical support is provided to anyone who asks.  Just send me email
with your problems or feedback.  Phone support is provided to registered
users.

The FREE technical support provided to registered users includes extra help
in using the full-size version of Mathomatic, answers to any math questions
you may have that I can find the answer to, and a free update if you find a
bug in Mathomatic.  Upgrades to registered users cost $20.

Mathomatic is educational!  It even shows you how it solves an equation if
you enter "debug 2" at the Mathomatic prompt before you solve an equation.
This sets debug level 2, to return to normal, just enter "debug 0".

The latest shareware version of Mathomatic and source code is always
available at the Mathomatic Home Web Site:
