This paper provides explicit combinatorial expansions of the Chern classes, Pontrjagin classes, Chern character, as well as the Chern character and Chern classes of a tensor product of two vector bundles. One will also find expansions of the \widehat{A}-genus, L-genus, Todd genus, their twisted forms, as well as relations among the three genera. The computational methods are elementary, but we hope that the clearly displayed and ready-to-use results — which do not seem to be otherwise available — will be useful. This is the first part of research based on the undergraduate project of the second and third authors advised by the first author.
