Notices :

1. On first run, goto menu --> preferences to best fit the appearance of the calculator. The size of the calculator may be also scalable by moving two fingers apart when they both touched the screen.

2. To get an idea of the program, click 'F1' --> 'help' --> ')' --> 'Exec' and the help sheet would be appeared on the right-handed side of the calculator.

3. To run a calculation, type the formula and click 'Exec' button.

4. An official cookbook for Mathcalc can be found on the developer site.
