Finding a rule from a table of values using a combination of operations - Cool math

The video tutorial explores the concept of functions, focusing on how variables X and F of X relate to each other. It examines different operations like addition, subtraction, and multiplication to determine function rules. The tutorial emphasizes the importance of finding a consistent rule that applies to all values, not just specific cases. Through examples, it demonstrates how to combine operations to establish valid function rules, encouraging practice for mastery.
