Note
Pressing
m or 1m(M–) while a calculation result is on the display will add it to or
subtract it from independent memory.
Important!
The value that appears on the display when you press
m or 1m(M–) at the end of a
calculation in place of
w is the result of the calculation (which is added to or subtracted
from independent memory). It is not the current contents of independent memory.
