WebJan 8, 1998 · the numerical uncertainty of the sum or difference is the sum of the numerical uncertainties of the two numbers. For example, if A = 3.4±.5 m and B = 6.3±.2 m, then A+B = 9.7±.7 m , and A-B = -2.9±.7 m. Notice that the numerical uncertainty is the same in these two cases, but the fractional uncertainty is very different. Rule2.
