The current result of a calculation which is represented in the result indicator line can be transferred next to calculation (memory storage) and added or subtracted there.

Subsequently it is possible to transfer the result of the next calculation (out of the memory storage) into a current calculation.

The functions of the memory-keys:

The current value from the result indicator line is added with the memory storage value (F5)

The current value from the result indicator line is subtracted of the memory storage value (F6)

The memory storage value current is received into the current calculation (Shortcut: M and ENTER) - with the operator to be subsequently input decides the calculation step further.  (F7)

The memory storage values deleted (F8)
