Number of sf to be carried forward

[hasan_researc]

Homework Statement

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??

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.
