Overview of Sig Figs

What I understand of Sig Figs is basically that they are all the numbers represented when a number is written in scientific notation. Trying to remember all the rules of whether a number is significant or not is a little too much to think about converting it to scientific notation is a lot easier.

As for math functions, sig figs get rather confusing, all I can say is remember that rounding is always to the least accurate number and that the least accurate number in adding (or subtracting) is the one with the least decimals while the least accurate number in multiplication (or division) is the one with the least sig figs. Other than that, remember states of matter, types of mixtures, and nomenclature. That should be it for the next quiz.

Also these link will help. The bottom two are a little elementary but they explain the topic quite nicely.
