Preface Note to Students

This book focuses on "pulling back the curtain" to reveal the underlying concepts behind everyday mathematics. The goal isn’t to have you memorize formulas or procedures—though you may find a few worth remembering—but to provide insights into how things work. From credit card finance charges to statistics in the news and ranked-choice voting, this book explores the mathematics shaping our world.
