Logarithm (noun)
The power to which a base number (e.g. 10) has to be raised to give a particular number. Often shortened to "log".
Examples:
The (base 10) logarithm of 100 is 2.
The (base 10) logarithm of 200 is approximately 2.3.
[Note: The above definition is not quite adequate for logarithms less than zero, but I don't want to get too technical.]
(Coined in 1614 by the mathematician John Napier, from Greek logos, reckoning, and arithmos, number.)
