Okay so when it comes to sig figs, it isn't about the problem telling you which places to round up to, but rather it is about how many digits are present in the values provided. For example, had said that problem stated 3.55g, that refers to 3 significant figures. Therefore, you would want to round to that value if what you are doing is multiplication or division. For addition and subtraction, you want to round it to the decimal places. For example, if the problem stated 7.4m, that means you want to round the answer to tenth place for your answer. As the initial post stated, you don't want to try rounding in the middle of the process because that often times messes up by a small margin which can be crucial to the problem.
