Mathematica calculates exactly and therefore does not simplify unless there
is an exact simplification.

For an approximate number answer use the N function.

In[1]:= Log[2]
Out[1]= Log[2]

In[2]:= N[Log[2]]
Out[2]= 0.693147

I have Mathematica 5.0.1.  When I attempt to get the Log of a number "a"
by entering Log[a], it does not return the value but echoes back:
Log[a].  How is this fixed?
