An inner product space is a vector space for which the inner product is defined. The inner product is also known as the 'dot product' for 2D or 3D Euclidean space. An arbitrary number of inner products can be defined according to three rules, though most are a lot less intuitive/practical than the Euclidean (dot) product.2. It's simple to discover determinants just by solving Ax = b by hand, using high school algebra, in the case where A is 2 × 2 or 3 × 3. You immediately see that the system can be solved for any choice of b if the determinant is nonzero (because you will try to divide by the determinant).

Therefore A cannot be right invertible, since if AB = I, then A ′ (BC − 1) = CABC − 1 = CC − 1 = I. Conclusion: if A has a right inverse B, we must be in the first case, so A is (two-sided) invertible.
