Introduction to College Mathematics with A Programming Language

When one thinks of the new math introduced in the public schools about
1960, the first mathematical notion that comes to mind is that of sets.
Using the notion of set, elementary school teachers are supposed to be able
to better explain the basic ideas of arithmetic. Thus, one could conclude
that every adult should know some set theory in order to carry on an
intelligent conversation with elementary school children (about mathematics). Sets do provide a good foundation for many topics in mathematics.
Therefore, set theory is an ideal topic to begin a survey of mathematics.
