The term "homological algebra in degree zero" refers, in the narrow sense of the word, to calculation of the zeroth derived functor of an additive functor between abelian categories. Most people do not realize that this is an interesting problem because the zeroth right derived functor of a Hom functor is the same Hom functor, and the same can be said about the zeroth left derived functor of the tensor product.
