Note that calculation history memory contents are
cleared whenever you turn off the calculator, press
the key, change to the calculation mode or the
input/output format, or perform any reset operation
Calculation history memory is limited.When the
calculation you are performing causes calculation
history memory to become fuli,the oldest
calculation is deleted automatically to make room
for the new calculation.
Replay Function
While a calculation result is on the dispaly,you can
press
1 ^ and then® or® to edit the expression you used
for the previous calculation. If you are using Linear
format,you can dispaly the expression by pressing ®
or®,without pressing ® first.
Example:4x 3+2.5= 14.5
4X3-7.1 =4.9

Description
Stores the last calculation result obtained.
Calculation results can be added to or
subtracted from independent memory.
The "M" display indicator indicates data
in independent memory.
Six variables named A, D, X, and Y
can be used for storage of individual values.
This section uses the COMP Mode ( MOPEim) to
demonstrate how you con use memory.
■ Answer Memory(Ans)
Answer Memory Overview
•Answer Memory contents ore updated whenever
you execute a calculation using any one of the
following key:H.ISHiFi1H.liH.6RiFTliB(M-) .B.6HiFi1B(STO)
Answer Memory con hold up to 15 digits.
•Answer Memory contents ore not change if on error
occurs during the current calculation.
• Answer Memory contents are maintained even if
you press the @ key,change the calculation mode,or
turn off the calculator.

•With the above procedure, you need to perform the
second calculation immediately after the first one.
If you need to recall Answer Memory contents after
pressinglAS, press the lAnsI key.

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.
