CORRECTING OVERFLOW ERRORS
If a calculated result exceeds the dis-
play ability or the memory capacity,
the display stops and E appears in
the display. Press [ ON/C ] to
resume calculating.
The range of calculated results and
memory capacity are within the
range of 1 x 10 -99 to 9.9999999 x
10 99
An error also occurs if you try to
divide a number by 0 or extract the
square root of a negative number.
CALCULATION EXAMPLES MIXED
2 x 8 - ( 3 + 5 ) x 4 - 6 x 7 = 20
4.3 - 1.8
hierarchy first, press [ = ] to perform
the higher hierarchy calculation, then
enter the lower hierarchy calculation
to get an accurate result.
Example: (10 + 5 ) ÷ 3 = 5
Incorrect: 10 [+] 5 [÷] 3 = 11.6667
Correct: 10 [+] 5 [=] 15
[÷] 3 = 5
With this method, calculations can be
performed in the proper order.
CORRECTING INCORRECT ENTRIES
If you press the wrong function key (
+, --, x, or ÷ ), just press the correct
function after pressing the wrong
one. The calculator preforms the last
function pressed.
Example: If you press the 5 + -- x 5
=, the displayed result will be 25 as [
x ] was the last function key pressed.
If you press the wrong number key,
press [ ON/C ] once to clear the last
entry, or twice to clear all entries
made. Entries made with the memory
keys are not affected.
