math module

[gombosk at vas.birosag.hu]

I have a problem with math module:

I import math module, because to call exp(x) or sqrt(x) does not work.

Do I need anything else to do?

>>> import math
>>> exp(10)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'exp' is not defined

This is the problem...
