5.1 Introduction
Operators work in a similar fashion to mathematical functions. They provide a relationship between two different domains. For example, the multiplication operator makes an ordered pair of operands (data on which the operator works) and produces another data point. This can be done to any number of data points. In this way, the operator transforms data from the domain of operands to the domain of results.
The symbols for basic operators are given in Table 5-1.
