... Let Dn denote the determinant of An , and sn = x0 + x1 + · · · + xn−1 . Prove that if the xk ’s are integers such that sn 6= 0, then sn |Dn . Solution by H.-J. Seiffert, Berlin, Germany Adding the second, third, fourth, . . . and last row to the first row in Dn , we arrive to the determinant En , wh ...

... • Q is not complete: limits that “ought” to exist in Q fail to do so, e.g., 2. • Q is not algebraically closed: polynomials that “ought” to have solutions in Q fail to do so, e.g., X 2 + 1. The smallest complete field containing Q is the real numbers R. But R is not algebraically closed, e.g., X 2 + ...
