Evaluating Variable Negation in System Adjustments
A junior data analyst is confused by a spreadsheet formula that uses the expression to reverse recorded errors. They believe that this expression will always result in a negative number. Based on what you have learned about evaluating , describe the procedure for substituting a value into this expression and finding the result. In your explanation, explicitly state the two different outcomes for the sign of the final result based on whether the initial value of is positive or negative.
