1+1=2
It is because that is how "plus" is normally defined. But 1 plus 1 need not be two. It all depends on the domain and range that you are working with and what you mean by the binary operation "plus". If 1 means make an about turn, and "plus" means "follow it with", then 1 plus 1 is "make an about turn" and then "make an about turn". If you do that you are back where you started. So in this case, 1 plus 1 is the same as zero.
You don't. 1+1+1+1=4, not 100 and never will.
