Interestingly, after I had this guide up for a while, this turned out to be the question I was asked most frequently, usually in terms that included phrases like "Greek to me", "beats me", or, as above, ... To understand what a logarithm is you first have to understand what a power is. ... OK, you do know what a power is.

Math Skills Review ... In simpler terms, my 8th grade math teacher always told me: LOGS ARE EXPONENTS!! What did she mean by that? ... Using log10 ("log to the base 10"): log10100 = 2 is equivalent to 102 = 100 where 10 is the base, 2 is the logarithm (i.e., the exponent or power) and 100 is the number.

We are most familiar with base 10 since any number greater than zero can be expressed as 10x. For example, log(10) is 1 (because 101 =10), log(100) is 2 (because 102 = 100), ... The opposite of a log is the antilog, which means to raise the base to that number. Antilogs "undo" logarithms. Observe the following example...

Logarithm - Wikipedia, the free encyclopedia
In mathematics, the logarithm of a number to a given base is the power or exponent to which the base must be raised in order to produce the number. For example, the logarithm of 1000 to the base 10 ...
