• “E” (Error) will appear if the calculation result exceeds the upper
calculation limit of the calculator. If this happens, press A.
• The value displayed when a calculation error occurs is a rough
approximate value.
Example: If 1.23 is displayed along with “E”, it indicates a value of
approximately 1.23 × 10
12
.
k Clearing Calculations
• To clear the calculator except for independent memory, press A.
• To clear independent memory only, press M twice.
k Reviewing a Calculation
Important!
• Before you can review steps in Calculation Memory, you must first finalize
the current calculation. See “k Finalizing a Calculation”.
