-- MathPad is a general purpose scientific calculator that uses text input rather than a graphic simulation of a hand held calculator. This allows you to see and edit your entire calculation.
-- MathPad runs on a Mac Plus or higher with system 6 or system 7.
-- The application file may be installed wherever is convenient. It does not require or create any auxiliary files. If you double-clicked on this README file you have already installed and are running MathPad.
-- Use the Finder's Get Info... box to set MathPad's memory size depending on your use:
-- 150K if you never use large files, image, read() or write().
-- 160K if you use advanced features and large files.
-- 200K if you use advanced features, large files and large arrays.
-- >200K if you run out of memory when set at 200K. Huge arrays?
----------- Upgrading to version 2.1 ----------------
-- The basic core of MathPad has not changed so existing documents should work fine with version 2.1. See the file "What's New" for a detailed list of what has changed.
----------------- Using MathPad --------------------
-- MathPad may be used as a calculator simply by typing in numbers and operators. When the ENTER key is hit, each line is evaluated and the results are inserted into the text.
2*(3+4):14.000
-- MathPad inserts the ":" and the result "14.0". A status line at the bottom of the window will show a "√" to indicate that evaluation is complete. If any problems are encountered, they will be reported in the status line and the cursor will be moved to the problem in the text. You can edit and re-evaluate the text at any time. The RETURN key simply terminates a line. It does not cause any evaluation. The ENTER key is on the numeric keypad (or next to the space bar on powerbook keyboards).
-- MathPad can do much more than act as a simple calculator. The built-in help file (choose Help from the File menu) gives some examples of more advanced features.
--The file "MathPad.doc" describes the full capabilities of MathPad mainly by giving short examples.
-- The "examples" folder contains some longer examples and utility functions. These examples show how to implement such things as equation solving, curve fitting, vector calculations and numerical solutions of differential equations.
-- The files "Image.doc" and "Datafiles.doc" give some extra detail on these capabilities.
