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

).
