Significant figures

  1. Sep 10, 2005 #1
    How many significant figures should be retained in the result of the following calculation.

    (11.13 - 2.6) * 10^4
    -----------------------
    (103.05 + 16.9) * 10^-6

    is it 1 , 2 , 3 , 4 or 5 ?

    Oops

    I just read the posting guidelines more closely, so instead i will give u a hint :-)
    You should look at the entire "formula" (I lack a better word), and find the number with least significant digits, thats the amount of significant digits in your final result.
