Sig Figs: Rounding Off

Postby Hue_Vo_1D » Sat Feb 11, 2017 11:09 am

If the problem has several calculation steps, should we round off at every step before moving to the next or leave it off until the end to round just the final answer?

You should leave it and round off your final answer.

If there is a question with a number that has the least amount of significant figures and that value is not used when calculating for the answer, do we use those number of significant figures still or the number of significant digits from a number that is used when calculating that is the least?
