What’s In
On the previous modules, the basic concepts on functions were introduced. Functions
were used as mathematical models. These are abstract models that use mathematical language
to describe relationships. With the notion of mathematical modeling, mathematics is concerned
not only with the measures of the physical world but it has also expanded its applicability to
sciences, both social and biological, business, and finance. So with this, lessons relating to
business and finance will then be introduced specifically on simple interest.
