Log[] in Mathematica is, by default, the natural logarithm (base e).
The log() function on your calculator is most likely the common
logarithm (base 10).  On a calculator, the natural logarithm is
probably ln().

You can use Log[] in any base by giving the base as the first
argument.  The common logarithm of x would be Log[10,x], for example,
or you can be explicit to use the natural logarithm by specifying Log
[E,x]

Check the zoom level, which would be in a little bar at the bottom of
your notebook.  I suspect it is set to a very small value.
