comment Non-associative, non-commutative binary operation with a identity
what's the point of adding y if it is zero! Are you sure this was what you meant?

comment A question about integral quadratic forms
The left part of your equation is what mathematicians call a (integral) quadratic form. There is a lot of results about the integers n they can represent or not.

comment Prove that if $(ab)^i = a^ib^i \forall a,b\in G$ for three consecutive integers $i$ then G is abelian
thanks a lot for these references. We speak of Exponent semigroup, Levi semigroup, etc. What is the operation on these sets?

comment Probability of a point taken from a certain normal distribution will be greater than a point taken from another?
Just to be sure: do you consider the two draws to be strictly independent, i.e. the mechanism simulated by the second draw is not modified or influenced by the value of the first? If this is the case, the problem can be rephrased very simply, while perhaps not realistic. Also note that there is Cross-Validated, the SE site for statistical Q&A.
