Memory

To make certain calculations easier, you can save a number in the Calculator’s memory. When the app starts, the number in memory is set to zero. You can display this number or change its value using the on-screen memory keys:

MC Resets the number in memory to zero. MR Displays the number in memory.

M- Subtracts the currently displayed number from the number in memory. M+ Adds the currently displayed number to the number in memory.

Note: The number in memory is reset to zero each time the Calculator app is launched from the Apps Home screen.
