Entering digits: There are 3 ways of entering digits: tap a screen button, use the graffiti pad, or use the keypad on devices so equipped.

Fractional digit entry: To enter a fractional value, you would use the decimal button twice. For instance, to enter 5.3/8, you would press "5, Decimal, 3, Decimal, 8, Enter". The value will then be displayed in the current display mode, which may, or may not, be fractional.

Operations: When you tap a button, the main operation (displayed in white) will be executed. If you tap the 'fn' button first, the functions shown on the bottom of the button will be executed. After the 'fn' button has been pressed, an 'f' will appear at the right of the display.

Alternate top buttons: Pressing the "up" button will scroll the top row of buttons.  The top row will, by default, show trigonometry functions, but they can be scrolled to show financial, statistics or programming buttons.

Menu: The menu bar is not visible in Bob's Calculator, so that more buttons can be displayed on-screen.  To open the menu you must tap the very top of the screen, or the menu button, which is usually located at the bottom left of the graffiti input area. On keypad equipped devices, the menu button is usually near the bottom corner.

Mantissa: If you tap the display area, the mantissa (the top 11 significant digits of the current number) will be displayed for a brief period of time, or as long as you hold the stylus at that spot. You can make the mantissa display persistent by, instead of lifting the stylus from that same spot, dragging the stylus from the display area down to the button area of the screen. The mantissa will be displayed until the next operation or screen tap.
