Independent Memory (M)

Tou can add calculation results to or subtract results

from independent memory. The"M" appears on the

display when independent memory contains a value.

Independent Memory Overview

The following is a summary of the different

operations you can perform using independent

memory.

To do this: Perform this key operation:

Add the displayed value

or result of the expression

to independent memory

Subtract the displayed value

or result of the expression from

independent memory

Recall current independent

memory contents

SHIFT]® (M-|

HH(M)

You can also insert the M variable into a

calculation, which tells the calculator to use the

current independent memory contents at that

location. The following is the key operation for

inserting the M variable.

[ALPHA] @ (M)

The "M" indicator appears in the upper left of the

display when there is any value other than zero

stored in independent memory.
