Let V be the set of all positive real numbers. Define α + β = αβ - 1 and c(α) = α. For example, 5 + 6 = (5)(6) - 1 = 29 and 3(7) = 7. Is V a vector space or not? Support your answer.
Yes coolge,matrix addition is associative however I limit my question to only vertices. But, can you show me a proof showing that associative property does not apply? sorry just confused how to apply the law of associativity in terms of vertices. thank you!
