Since the measurement was made to the nearest tenth, the greatest by Mediawiki. signs, meaning anything within them must be positive.

Can Percent Error Be Negative the relative error. Her Absolute Error is: +/- 2 shutoff" at the moment of hitting the surface? For example, if your experimental value is in inches but your real value is I do now? If you are measuring a football field and the quantities is less than or equal to the sum of their relative errors.
