Chapter 3.1, Problem 13E

Let R denote the set of real numbers. Define scalar multiplication by α x = α ⋅ x (the usual multiplication of real numbers)and define addition, denoted ⊕ , by x ⊕ y = max ( x , y ) (the maximum of the two numbers)Is R a vector space with these operations? Prove your answer.
