Using calculator memory

It is possible to store one number value at a time in the
memory of the calculator and then recall it, and add or
substract a value to/from this value in the memory. When
any number value besides zero (0) is saved in the memory,
the letter M appears at the upper left side of the input
field. If zero (0) is saved, it means the same as clearing the
memory.

These are the memory commands:
MR — Recalls the value in memory to the input field.
