We show th is by making the log negative rather than positive. So, log (10000) = 4 (count the zeros after the first digit) log (0.0001) = -4 (count the decimal point and the zeros after it, but stop when you get to a non-zero digit) So big numbers produce positive logs and small numbers produce negative logs. There must also be a log that is ...
