Re: Sig Figs
Whatever numbers are given in the problem allow you to determine sig figs. If you are multiplying or dividing numbers, you limit your sig figs to the smallest number of sig figs in the calculation. If it is addition or subtraction, you limit sig figs to the term in your calculation with the smallest number of digits after the decimal point.

Re: Sig Figs
A couple things to keep in mind when determining how many sig figs are in a given number are: all nonzero digits are significant, leading zeros are not significant and captive zeros are significant. Hope this helps!

Re: Sig Figs
I remember that I came across a question that listed no numbers, so I was told to use 4 significant figures. The answer in the book also listed 4 sig figs, so I would use 4 sig figs if no numbers were given.

Re: Sig Figs
You just go with the values you see that have the least amount of significant figures.
For example, if you have a question that involves calculations with the numbers 1.3005 and 7.69, then you would do the entire question and all the calculations without rounding until you get the answer- to which you would see that 7.69 has the lowest number of significant figures (3) and would round the answer to 3 significant figures as well.

Re: Sig Figs
The question will give a value or values of something with sig figs. The lowest number of sig figs in the given value(s) should be used for the answer.

Re: Sig Figs
You round your answer to the lowest number of significant figures that are present in the given numerical values from the question.
