Number of sf to be carried forward

  1. Jun 20, 2010 #1
    1. The problem statement, all variables and given/known data

    My problem is with the number of significant figures I have to carry forward in intermediate calculations. I know that if the given data has a minimum of n sf, then the final ans should be to n+1 sf. But then should the intermediate answers be to n+2 sf??


    2. Relevant equations



    3. The attempt at a solution

    I have no idea how to solve this problem.
    Please help!!

    If it's simply part of your working i'd of thought as many significant figures as possible, you won't lose any marks having all intermediate answers to n+3 SF as long as you have an accurate rounded answer. Much better that than having all intermediate answers to n SF which will almost inevitably affect the accuracy of your final answer to n+1 SF.
