We consider the following construction of quantization. For a Riemannian manifold $M$ the space of forms on $T^*M$ is made into a space of (full) symbols of operators acting on forms on $M$. This gives rise to the composition of symbols, which is a deformation of the (``super'')commutative multiplication of forms. The symbol calculus is exact for differential operators and the symbols that are polynomial in momenta. We calculate the symbols of natural Laplacians. (Some nice Weitzenb\"ock like identities appear here.) Formulas for the traces corresponding to natural gradings of $\Omega (T^*M)$ are established. Using these formulas, we give a simple direct proof of the Gauss-Bonnet-Chern Theorem. We discuss these results in the connection of a general question of the quantization of forms on a Poisson manifold.
