Using Memory Storage Keys (M1-M9)
In addition to the standard cumulative
Memory (as previously described),
your calculator has nine independent
Storage Registers – M1 through M9 –
that can be used to permanently store
single, noncumulative values. The
following example shows the use of M1
( gr1 ). To use M2 - M9, replace the
presses of the 1 key with presses of
the corresponding number key ( 2 - 9 ).
