Edge Loops

What is the purpose of changing these settings?
            The purpose of changing the setting of an tool is that you will make the tool work different than what it is used to work as.

How does each new setting change how the tool works?
              Each new setting will change the way the tool works because it helps the tool work different by
changing the way the object looks
What happens when you change the Multiple Edge Loops, Number of Edge Loops, and the Auto Complete?
                What happens is that there is either more edge loops or less edge loops, it puts more or less number of edges, and it turns on the auto complete or it turns it off
