In this paper, we at first study properties for curvature tensors, Ricci curvature on the singly warped products on semi-Riemannian manifolds. And then, we establish the whole formulas of the curvature tensor, Ricci curvature and scalar curvature on the singly and warped product on semi-Riemannian manifolds.
