Suppose that a set G has a binary operation on it that has the following properties: 1. The operation ◦ is associative, that is: for all a,b,c ∈ G, a◦(b◦c)=(a◦b)◦c 2. There is a right identity, e: For all a∈G a◦e=a 3. Every element has a right inverse: For all a∈G there is a^-1 such that a◦a^-1=e Prove that this operation makes G a group. You must show that the right inverse of each element is a left inverse and...
