Notices :

1. On first run, goto menu --> preferences to best fit the appearance of the calculator. The size of the calculator may be also scale-able 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.
