18.2 Memory functions

The memory functions allow to store and recall calculations.
The calculator memory is at 0 until you hit the hotkeys for M+ or M-. Each time
you hit M+ the number on the display is added to the number in the calculator
memory. Each time you hit M- the number on the display is subtracted from the
number in the calculator memory. To recall the number in the calculator memory
hit MR. To zero out the memory hit MC.
Please check the following list of supported Memory functions

MC (Memory Clear)

To clear the memory value, press Space + Right arrow

M+ (Memory Plus)

To add the current value to whatever is stored in memory, press Space + Up
arrow

M- (Memory Minus)

To subtracts the current value from whatever is currently stored in memory,
press Space + Down arrow.

MR (Memory Recall)

To recall the value from the memory and show it on the display, press Space +
Left arrow.
The π (Pi) is one of the most common constants in mathematics. Press Dots 1 2
3 4 to enter the value of Pi directly, so you don't usually have to remember all the
digits of pi i.e. 3.1415
