Number of Sig Figs in Answer

Postby Seungyeon_Chi_1K » Fri Oct 13, 2023 1:52 am

I thought we were supposed to answer with the most amount of sig figs given in the question, but in a pdf that I saw in bruinlearn, it tells us to answer with the least amount of sig figs given. Which way am I supposed to answer when answering questions for this class?

i'm pretty sure it's the least number of sig figs in the operation that determines the number of sig figs in the result.

The reason why you must always use the least amount of sig figs given in the calculation is so that the final result doesn't appear more precise than the original measurements of data. This exaggerates the precision of the final answer and misleading you from the true accuracy of the result.
