Why are round-trip fares from Orlando to Kansas City higher than those from Kansas City to Orlando? How do interest-rate adjustments affect the real estate market? How does one calculate the price-to-earnings ratio of a stock and use it to predict future performance? Mathematics plays an indispensable part in answering these questions. This course will give you a strong foundation in central concepts of business and finance, like the mathematics of buying and selling, how simple and compound interest affect the value of loans, mortgages, and interest-bearing accounts; and the impact of taxes on personal and government budgets. While examining these topics, you’ll manipulate and solve algebraic expressions and learn to apply a range of mathematical concepts, including direct and indirect variation and arithmetic and exponential growth. Through simulations, projects, and investigations, you and your classmates will grow more secure in your own financial management and enhance your understanding of the broader economic conditions that shape personal, public, and corporate investments.

About Mathematics at CTY
Explore the study of shapes
Many of our courses allow students to describe the world around them in basic and profound ways. Younger students build foundational skills by exploring shape, scale, and proportion in Geometry and Spatial Sense. Middle School students delve into real-world applications of lines and analyze data with curves that follow uniform, symmetric, bell-shaped, or skewed patterns in Data and Chance. Advanced students unveil the deep interplay between numbers and shapes, investigating how triangular, square, and polygonal numbers create patterns that bridge geometry and algebra in Number Theory. By examining these elegant number patterns and symmetries, students discover how mathematics captures the intricate beauty and underlying structure of the natural world.
Dive deep into logic and reasoning
Our courses in formal logic give you the tools to question the world around you. Inductive and Deductive Reasoning introduces younger students to different types of reasoning, as well as the strengths and weaknesses inherent in various forms of critical analysis. Older students explore how logical reasoning can explain (or fail to explain) counter-intuitive results in Paradoxes and Infinities, or take a more rigorous approach to formal logic in Mathematical Logic.
Meet our instructors and staff
This was my fifth summer working at CTY. I love the culture of CTY. For three weeks, students and staff from all over the world create their own special community unlike anywhere else. I love getting to be a part of that.

There is nothing better than seeing that 'eureka' moment and the extension of that moment as students exuberantly share their thoughts.
Dan Sievers
Math Instructor
When I was a student at CTY, I was excited to be in a place where all of the instructors and program assistants loved learning as much as I did. It wasn't until I came back as a PA that I realized CTY instructors feel just as excited to work with such dedicated and curious students.
