Thank you for the opportunity to help you with your question!

Logrithms are exponents!!!!! They are the exponent you hang on the base to get the number in question. That is, saying log x = y is the same as saying 10^y = x.

So log x = -2 is the same as saying 10^(-2) = x or x = 1/100.

Please let me know if you nea case for torture by michale levined any clarification. I'm always happy to answer your questions.
