you may assume that matrix multiplication is associative and that The determinant | a If ad bc 0, - -1 = ad - bc , (a b)² = 1 (a b) For matrices A and B in M₂ (R) the determinant of a product is the product of determinats involved, i.e. |AB| = |A||B| Is Gl₂(R) abelian? If the answer is NO, give an example.
