Systems of computer mathematics find more and more broad application in a number of natural, economical and social fields. These systems are rather important tools for scientists, teachers, researchers and engineers, very well combining symbolical methods with advanced computing methods. One of leaders among tools of this class undoubtedly is the Mathematica. The book focuses on an important aspect – procedural and functional programming supported by Mathematica. This aspect is of particular importance not only for appendices but also above all it is quite important in the creation of the user tools that extend the most frequently used standard tools of the system and/or eliminate its shortcomings, or complement with the new facilities.
