Why do you suppose our math class starts with set theory?

What will you learn in this section that will have practical application in your life?

Going a step further, why are the vast majority of college students, no matter what their field of study, required to take at least one math course?

 

Example Answer: 

In reference to mathematics, “a set is a collection of objects” (Sobecki & Bluman, 2015, pg. 44). The collection of objects is distinct and well defined. Set theory is the base of the mathematical structure which is why math classes start with it.  A set can be defined by three different methods; list or roster, descriptive, or set-builder notation.

I often use set theory in my life without even thinking about it. I am a lead person in my job, who trains new employees and also advanced employees. I place people in sets by experience and skills and base my training on it. A good example would be:

A=All employees in my department

B=New employees to department

C=Long term employees wanting to obtain specialty training

A is a set whereas B, C are subsets. The training for the subsets is based on length of service and skill level.

Math is a part of daily life whether it is balancing a check book, figuring out sale prices, or solving equations for a career. I use math in my job each day when calculating doses of medications, ventilation volumes, and calculating percentages of adverse reactions.
