Finite Mathematics

Finite Mathematics covers mathematical concepts and techniques applicable to business and social sciences, including matrix algebra, linear programming, and probability.

Basic Concepts

Sets and Logic

Understanding Sets and Logic

Sets are collections of distinct objects, such as numbers or people, grouped together because they share a common property. Logic is the set of rules we use to reason and make decisions based on facts and relationships.

Sets in Action

Sets help us organize and analyze information. We use special symbols and terms, like union (\(A \cup B\)) for combining sets, and intersection (\(A \cap B\)) for finding common elements.

Basic Logic

Logic statements can be true or false. We use logical connectors like "and" (\(\wedge\)), "or" (\(\vee\)), and "not" (\( eg\)) to build more complex statements and make sound decisions.

Real-World Importance

Sets and logic are everywhere: from sorting emails into folders to creating search filters online. They form the foundation for all the other topics in finite mathematics!

Examples

  • A group of students enrolled in either Math or Science classes can be represented as two sets, with some students possibly in both.

  • A search filter using 'price < $10 AND color = red' applies logical operators to find the right items.

In a Nutshell

Sets and logic help us organize and reason about information.

Key Terms

Set
A collection of distinct objects.
Union
All elements from two or more sets.
