Calculate Plus/Minus (CalcPM) is a scientific calculator with in-built uncertainty (error) handling. Uncertainties are combined based on the method of standard uncertainties. CalcPM operates in either traditional input format (BOMDAS) or reverse polish notation (RPN). Uncertainty usage can be disabled for standard calculator operation. A one-touch summation mode is also available for quick summation of numbers 1-10.
