But in advanced mathematics there is only one logarithm. False. The ln/log/alog was introduced when base ten logarithms was applied to calculation like: 2*5 = ... log 2 = 0.3010, log 5 = 0.6990, 0.3010+0.6990 = 1.0000, alog 1 = 10 ... therefore 2*5 is just 10 BTW, I still memorize log 2 and log 5 and log pi, so I have no need look for above values in tables and/or calculators/computers. :) I trully advanced mathematics there are infinitely many logaritms, because you can pick any base. It is a rather sense of taste to use e = 2.71... as a base, sometimes it may be a convenient choose, sometimes not. I is the similar to choose decimal numbers instead hexes. slawek
