This also clears thememory.To clear an error caused by trying tocalculate the square root of a nega-tive number or by trying to divide by 0,press ON/AC. This also clears thememory.Estimating CalculationResultsIf your calculation results in an over-flow error, you can estimate the ap-proximate result by following thesesteps.1. Count the number of digits dis-played to the left of the decimalpoint.2. Remove the decimal point.3.
