so i finished logarithms a few weeks ago for mathematics/precalculus 12( also known as algebra II in the states i think ) and i got 100% on the test but don't feel i understand logs very much... i understand how to solve problems and the laws completely but i started reading a book called "In Pursuit Of The Unknown, 17 equations that changed the World" which has a chapter on the history of logarithms and i have came to the conclusion that i do not understand logarithms very much...

ex:

log4 = .6020599913

i understand its log base 10

therefore i know 10^.6020599913 = 4

1)but i don't understand why the word "log" is in there, what is the

*value*of log? or is there a value?

2)what exactly does log4 mean? does it just mean 10 to the power of something = 4?

3)Also, will university math courses go more in depth with say logs, translations, arithmetic sequences and series and such?

i have over 95% in this course yet i feel like i am not learning enough. There is no proofs, i have no idea why we use the formulas we do. Its simply just, this is how you do it or here's the formula, now solve the problem. it seems so juvenile.

any help would be greatly appreciated
