*Android, Google Play and the Google Play logo are trademarks of Google Inc.
This is an emulation of a simple pocket calculator. It supports the most common arithmetic operations and can be used for basic everyday math calculations.
You may operate this calculator using mouse or keyboard but a numeric keypad is recommended for faster typing and a more comfortable experience. When typing using a keypad use the 'Enter' key in place of the '=' sign. Most operations can be performed without moving the hand away from the keypad. If necessary press the NumLock key on your keyboard to enable the keypad. Note: Before using the keyboard you may need to click on the calculator once with your mouse. You can also left-click with your mouse on the buttons.
For more information on the simple virtual calculator see the instruction manual.
Example: To calculate the value of 88 x 9:
You may use your keyboard instead of the mouse to enter numbers and the keys for 'c', '+', '-', 'x' (multiply) and '/'.
