      the terms in the determinant of a 3 × 3 matrix is given in Figure 3.4.1. By taking the product of the elements joined by each arrow and attaching the indicated sign to the result, we obtain the six terms in the determinant of the 3 × 3 matrix A =[aij]. Note that this technique for obtaining the terms in a 3×3 determinant does not generalize to
