After understanding the exponential function our next target is the natural logarithm. ... The natural log is the inverse of e, a fancy term for opposite. Speaking of fancy, the Latin name is logarithmus naturali, giving the abbreviation ln.

The system of natural logarithms has the number called "e" as its base. (e is named after the 18th century Swiss mathematician, Leonhard Euler.) e is the base used in calculus. It is called the "natural" ... To indicate the natural logarithm of a number, we use the notation "ln." ... Problem 10. What number is ln e ?

This last statement justifies calling the natural logarithm "the logarithm with the base e" and writing in more conventional terms ln(a) = log e(a). For example, e 0 = 1 so, ln(1) = 0 and e1=e so ln(e) = 1. In general ln(e a) = a , which merely restates part (b) of the theorem.
