1. It is not dual, it is homo??? (TONG GOU) in algebra

2. You can refer to (advanced) algebra for a more theoretic desc treatment of 
the topic.  You will see everything is  integrated ni ely
in that theory!

3. I am not sure what is your 0, but for any b != 0, your a+b <> 0.
That is, there is no reverse element for your +. Thats not conforming to
the requirement of a field, where each non-zero element has a reverse 
element such that a + (-a) = 0
