Calculation results can be added іо or
Independent subtracted from independent memory.
Memory The "M" display indicator indicates data|
in independent memory.
* Note that calculation history memory contents are
cleared whenever you turn off the ыш press
the key, change to the calculation mode or the
input/output format, or perform any reset operation
e Calculation history memory is limited. When the
calculation you are performing causes calculation
history memory to become full, 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 [лс] and thena orc to edit the expression you used
for the previous calculation. If you are using Linear
format, you can dispaly the expression by pressing @
orc» ,without pressing (AC first.

Bl Answer Memory(Ans)
Answer Memory Overview
* Answer Memory contents are updated whenever
you execute a calculation using any one of the
following key:(), SHIRE], s Hrm (M-) ,11,54Н(5ТО)
Answer Memory can hold up to 15 digits.
* Answer Memory contents are not change if an error
occurs during the current calculation.
* Answer Memory contents are maintained even if
you press the a key, change the calculation mode, or

* 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
pressing(AC) , press the key.
Inputting Answer Memory Contents into an

E Independent Memory (M)
You 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 Ma
to independent memory
Subtract the displayed value
or result of the expression from | — SHIFT|[M] (M—)
independent memory
Recall current independent КОП (М)
memory contents
* 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] [M3 (M)
* The "M" indicator appears in the upper left of the
display when there is any value other than zero
stored in independent memory.
