Mathematics is a powerful tool for helping us to understand
the world. In the following discussion, we will investigate
two methods of using mathematical models. We will see
that the two methods are really the same method, but
applied in different directions.
The first method we will explore is predictive. The idea is that there
is some real situation we think we understand. We convert our
understanding into some assumptions then use those assumptions
to develop a mathematical model of the situation. We use this model
to make predictions about the situation.
