Let T be the set of real numbers. Consider T as an algebraic structure with addition operation and multiplication operation given by x + y = min{x,y}, x©y=x+y - 2. Name the identity element in T for the operation, and prove the inverse law for O. 2 Prove the distributive law in T. [Hint: consider two cases x ≤ y, x > y.] 3 Prove that the set T with addition and multiplication Ⓒ is not a ring.
