Exercise 33. As a concrete example of the last observation, consider the sub-algebra A of M₂ (R) of real polynomials in the matrix M, where: M = 0 What is the dimension of A? Give a concise description of how multiplication of elements of A works. (Think of how you would compute something like I+5M97 - 2M1001, by hand!)
