well a vector space is something tht looks like R^n

Is this a vector space? Let M2 denote the set of all matrices of 2 x 2. Determine if M2 is a vector space when considered with the standard addition of vectors, but with scalar multiplication given by α*(a b) = (αa b) (c d) (c αd) In case M2 fails to be a vector space with these...
