Sig Figs and Rounding

[Sophia Dinh 1D]

Is it best to leave as many decimal places as possible during the steps and round sig figs at the end or would it be better to just round to the number of sig figs at each step?

Round significant figures at the end

Typically, it's best to save rounding for the end, just so your answer is as precise as possible! ;)))) If we round in the middle steps, the answer may turn out different than intended.

I think either way it should be fine. As long as your steps are correct, having your final answer off by .1 should not be a problem.

Hi Sophia! In my opinion, it is much better to keep as many S.F. as possible and then round at the end. In other classes that ask you to submit answers online, the websites (Pearson) get really nit-picky about getting exactly the right number and will mark answers wrong if you are even off by .01. Hope this helps!
