log0 is not defined

log 0 is undefined. The domain for the logarithm is ( 0 , infinity ).
When people write log 0 = - infinity, they mean that the limit, as x approaches 0 from the right, of log x is unbounded from below.
Recall what logarithm is. log a = b <=> 10^b = a
So log 0 = b <=> 10^b = 0 Thus we need to find what power of 10 yields 0. There is no real value of b that gives 0, but in the limit to -infinity 0 is approached.
log 0 is undefined.

The answer is negative infinity. Look at the graph in the link below and (hopefully) you will understand why.
lim log x (x->0) = -oo

negative infinity.
10 ^ negative infinity is 1 / infinity approaches zero.
