Memory Storage Keys (M0-M6)
In addition to the standard cumulative Memory (as described above),
your calculator has six independent Storage Registers — [M0]
through [M6] — that can be used to permanently store single, non-
cumulative values. These values will be held when your calculator is
turned off, and will only clear when a “Clear All” is performed (via
s x ).
You can replace a value in one of these Memory Registers by stor-
ing a new value in place of the stored value.
FUNCTION KEYSTROKES

*Perform a s x (Clear All) with caution, as it will clear any stored values from your
calculator’s registers.

Store 175 into M1, recall the value, and then store a new value in
place of the first stored value.
