Introduction21Figure 1.5.more. Of course, computer algebra requires some getting used to. But so did thecalculator (and the slide rule even more so!). But the gains are extensive. Once thebasic syntax is mastered and a core set of commands, much can be accomplished.Furthermore, it is not necessary to learn everything in these software packages.They are meant to be tools for a variety of disciplines. The present book illustratesthe type of tools they provide which are useful for the economist. By allowingcomputer software to carry out the tedious manipulations – whether algebraic ornumeric – allows concentration to be directed towards the problem in hand.BothMathematicaandMaplehave the same basic structure. They are composedof three parts:(1)akernel, which does all the computational work,(2)afront end, which displays the input/output and interacts with the user,and(3)a set oflibrariesof specialist routines.
