### Sig Figs

For determine the amount of sig figs we use for our answer, do we go with the least amount of sig figs from the numbers in the problem or the most amount of sig figs?

I'd def go least. Conventions dictate that the least accurately known number be reflected in the accuracy of the answer.

It's least because the whole point of sig figs is to maintain accuracy. The reason you go with the lowest sig figs is because for that number you are not sure about the other digits after it (ex. 4.5, you don't know what comes after the 5 --- it might be 4.5006), so you can't be sure about the accuracy of your answer if you go with the most sig figs.

You use the least number of sig figs found in the numbers in the problem.
