calculating the determinant for our 3x3 example a = np.array([[1,6,3],[3,2,5],[8,9,9]]) np.linalg.det(a) 83.99999999999999 As you can see the value we got for our determinant of the 3x3 matrix is 83.9999999 and not 84. Why is that? That is due to the floating-point error. I am not going to dig into
