Usually the positive and negative errors are the upper and lower limit of the value that you are looking at.

10.70 + 0.05 could be anywhere between 10.65 and 10.75

this is only a basic explanation (because I don't really know anymore ;))

someone else might have a fancy "error analysis" way of explaining it.
