Physical damage (Diablo 2)

Hi all. Tell me where you can see the full guidance on the calculation of physical damage.
Example:
- Basic weapon %ed damage (runeword ed);
- additionally, there are parameters % to demon;
- regular ED (forti);
- aura of fanaticism;
- ED my passive and active skills.
As if to calculate all of the damage does not show up in damage. More precisely, it does not appear % to demon, I read that it comes with the base damage and the flat type (add damage) BUT! In what is the final digit it converts the total damage other components?
