Addition and Subtraction When measured quantities are used in addition or subtraction, the uncertainty is determined by the absolute uncertainty in the least precise measurement (not by the number of significant figures). Algebraically, the absolute value is shown by placing two vertical bars around the calculation, as follows: - For this calculation, represents each of the experimental values, and is the calculated mean. The numerator of the standard deviation fraction is the sum of the squared differences between each value and the mean.
