Please explain significant figures to me

Hi, so I am taking AP Chem but I'm still iffy on sig figs since my teacher didn't teach it very well last year, and my teacher this year is subtracting points off tests if we have incorrect sig figs.

Can someone briefly explain how to determine how many sig figs to use when we do addition, subtraction, multiplication, division, as well as when we use log functions, and scientific notation?

Much appreciated!
