...Then, you can check a rule: log 10 + log 100 = 1 + 2 and log (10 * 100) = log 1000 = 3, so it appears that (log a) + (log b) = log (a*b). Do you plan on taking AP Physics or college freshman physics? If so, I would say that the math topic that's most likely to cause trouble is trigonometry. For... (read more)
