2) A) would you say the set of all 2x2 matrices forms a vector space? Explain. B) Given your work above do you think the set of all mxn matrices will form a vector space? Explain. C) We defined span and looked at the span of a set of vectors geometrically and numerically working with vectors from Rn. When a set of vectors spans a space the linear combination of them generates every object in the space.  Can you think of a set of 2x2 matrices such that when you take the span of them you can generate any 2x2 matrix? (hint: think of our standard basis for R2, R3, ... etc.)
