Making Corrections During Calculations
• If you make a mistake when inputting a value (but did not
yet press an arithmetic operator key), press
k
to clear
the value and then input the correct one.
• In a series of calculations, press
k
while an intermediate
result is displayed to clear only the last calculation per-
formed.
• To change the operator key (
+
,

-
,
\
,
A w
,
A s
, etc.) you just pressed, simply press the correct
operator key. In this case, the operator of the last key
you press is used, but the operation retains the order of
precedence of the operation for the first key you pressed.

b. When function calculations are performed using a value
that exceeds the input range. (“–E–” indicator appears
on the display.)
c. When an illogical operation (such as an attempt to calcu-
late
o
and
n
while
n
0) is performed during statistical
calculations. (“–E–” indicator appears on the display.)
d. When an illegal mathematical operation (such as division
by zero) is performed. (“–E–” indicator appears on dis-
play.)
