Errors
Your calculator displays ERROR if you:
Try to divide by 0
Perform a calculation that result in an answer
greater than 99,999,999
Note: You can determine the approximate
answer by counting the number of digits dis-
played to the left of the decimal point. Put that
many zeros on the right side of the number, then
delete the decimal point. For example, if the cal-
culator displays ERROR 3423.8381, the
approximate answer is 342,383,810,000.
To clear the error and continue the calculation with
the display number, press CE. To clear the entire
calculation and begin again, press ON/AC.
