In this paper we outline an approach to calculus over quasitriangular Hopf algebras. We study differential operators in the framework of monoidal categories equipped with a braiding or symmetry. To be more concrete, we choose as an example the category of modules over quasitriangular Hopf algebra. We introduce braided differential operators in a pure algebraic manner.This gives us a possibility to develop calculus in an intrinsic way without enforcing any type of Leibniz rule. A general notion of quantization in monoidal categories, proposed in this paper, is a natural isomorphism of the tensor product bifunctor equipped with some natural coherence conditions. The quantization "deforms" all algebraic and differential objects in the monoidal category. We suggest two ways for calculation of quantizations. One of them reduces the calculation to non-linear cohomologies. THe other describes quantizations in terms of multiplicative Hochschild cohomologies of the Grothendieck ring of the given monoidal category. These constructions are illustrated by some examples.
