Uncertainty in measurements

  1. Sep 30, 2006 #1

    I just had a quick question in regards to the addition/subtraction of quantaties and their uncertainties.

    Am i correct in saying (22.4mL plusminus .01mL) + (21.3mL plusminus .01mL)=43.7 plusminus .02mL?

    or is it plusminus .01mL ?

    Im pretty sure my first answer is correct just looking for a posative verification, thanks for looking.
