If you used a 0.1 mL labeled pipette, you could get a volume of 6.99 to 7.01 mL quite reliably. The sum or difference is to be rounded to the same number of decimal places as that of the measurement with the fewest decimal places which reflects the fact that the answer is just as precise as the least-precise measurement used to compute it. Leading or trailing zeroes can often be removed, and the number will remain accurate, although there are sometimes differing significant figure rules depending on your use. Once you know that, round to that many digits, starting from the left. 5) If the number does not have a decimal point, trailing zeros are not significant.
