A good rule of math is to not round until the end. Do all the calculations and then round what you're answer is. A rule of thumb is round to two decimal places. If this is a science problem, you may need to round to the correct number of significant figures. If you don't know what significant figures are, don't worry about it and just round to two decimal places.
