Let M','" (F) denote the set of n × m nnatrices with entries from the field F, we define miatrix addition and multiplication of a matrix by a scalar (i.e., element of F) as you saw in Math 211. It is a fact, which you do not need to prove, that with these operations Mn m (F) is an F-vector space. Find the dimension of M,n(F). 6.
