Enemy hp. how is that calculated?

I did try a little searching in here, but didnt find what im looking for, so I will ask. How is the hp of the enemys calculated? There is one calculation in the bio of the monsters theres also the number for each difficulty/players in game (as far as I know). Can someone show an example of how the end result hp turns out the way it is? Because I have looked at the numbers and it don’t make much sence :slight_smile:
