Packages Maple and Mathematica are indisputable leaders among modern systems of computer mathematics. In this connection there is quite natural question about preferability of either of these systems. This question is rather multidimensional in view of multifunctionality of both packages. In this connection in the book the comparative analysis of both packages concerning opportunities of their software environments for modular programming of the user problems of various orientation is submitted.
