The value stored in the ‘M’ memory can also be changed by adding or subtracting the result of a further calculation:

  • To add the result of the latest calculation to the value currently in the memory, press .
  • To subtract the value of the latest calculation from the value currently in the memory, use the key sequence (M-).

Expressions can also be stored in, added to or subtracted from the memory at the same time as they are evaluated by replacing the at the end of a calculation with one of the memory access sequences. For example, to calculate and store the result straight into the memory, use the key sequence (STO) (M).

To clear the ‘M’ memory alone, simply store the value 0 in it using the key sequence (STO) (M).
