sig figs in calculations

Postby Jesalynne 2F » Thu Oct 03, 2019 5:11 pm

Should I just use significant figures in my final answer or should I use them throughout the entire process leading up to my answer?

It's best to use them only in your final answer, otherwise rounding at each step may cause your final answer to be less accurate. The final answer will also be the only one where graders actually care about the correct number of sigfigs.

You only use them for your final answer because you want to use the most accurate calculations throughout the process of finding your answer instead of rounding at each sep and getting further and further away from the answer.

Only use sig figs for your final answer! You want to keep your calculations as accurate as possible, so the continuous rounding in each step would mess up the accuracy of your final result.

You should only use sig figs in your final answer to avoid error and not have incorrect numbers in your final answer.
