Logarithms deal with exponents: raising one number to the power of another number. Ten raised to the power of three is: ... Logarithms are exponents. Therefore, we can use the neat tricks associated with exponents. For example, when we multiply two numbers with the same base, we add their exponents.

So what are logarithms? Well, first let’s look at exponential equations, such as where the 2 is a base. We all know that for example, . A general form is where b is the base. Well, with logarithms, the format is . So for , we would express that with logarithms as . Fun, isn’t it!

Logarithms can have any base, but the most useful ones are 10, 2 and e. e is a constant used in math and finance; its value is approximately; 2.718. Logarithms to the base e are called "natural logarithms." On your calculator the base 10 log key is probably labeled "log" and the natural log key is probably labeled "ln.";
