Module 3: Importance of

Mathematics in the World

Objectives:

At the end of the lesson, the students should be able to:

1. identify and discuss applications of Mathematics in various fields;
and
2. apply mathematical concepts in solving societal problems.

We have seen how human knowledge has evolved throughout time.
We have observed in the previous lessons how evident Mathematics is in the
natural world, not only in patterns, but on how nature followed logical and
mathematical structures. It is therefore necessary to understand the many
applications of mathematical methods in different fields such as science,
engineering, business, computer science and industry.

This section discusses mathematics as an integral part of our everyday
life, as a necessary tool needed to communicate and interact in the society
we live in.

Mathematics helps people to predict different phenomena in the world
and to understand the behavior of nature. Through Mathematics, people are
able to exert control over the occurrences of events in the world and enable
advancement in the society to take place. Mathematics is indeed applicable
in various applications fields. Some of these includes forensic science,
medicine, engineering, information technology, cryptography, archaeology,
social sciences, political science and other fields.

1. In forensic science, mathematics is applied specifically in collection,
measurement, analysis and documentation of evidences. Forensic scientist
use proportions in their analyses. For example, if a human leg bone is
discovered in an unmarked grave, forensic scientists use math equations to
determine what proportion, or percentage, of a person’s overall height the
leg bone would be. This will enable them to know if the person is a child or
