Question

Why is it important to be able to identify sets and set theory as related to business operations?

Answer 1

Sets and set theory is used heavily in business.

For example, chart of accounts.  This is how businesses classify their financial transactions.

A chart of accounts often classifies transactions based on multiple criteria such as business unit, dept, type of transaction, etc.  Each of these is a subset of all transactions that may or may not intersect with each other.  Without a good understanding of set theory some transactions could be double counted when putting ogether financial reports.
