Also, I want to see if a one sided element for * exists, if it is unique.
Homework Equations
The Attempt at a Solution
Ok, I just don't really know what a one sided element is.
I'm using e*s=s*e=s, but is e*s the left identity?
I think my problem with finding uniqueness is getting started and the fact that I don't really understand what a one sided identity element is?
