You subtract Nan's from Paul's. So...
86m - 82.1m
=3.9m
We can't divide up the meters, since our worst measurement is plus or minus a whole meter. So we round the answer up. (If Nan's kite had gone 86.0 m, accuracy would be to tenths of
meters for both arguments and the an
swer).

86m - 82.1m = 4m = 400cm
