Understanding Input-Output Rules

The video tutorial covers the 'What's My Rule' lesson from Everyday Math. It explains how to apply different mathematical rules, such as subtracting seven and adding nine, to solve problems. The tutorial also guides students on how to discover rules from given numbers and encourages them to create their own rules. The lesson emphasizes understanding the relationship between input and output numbers and practicing these concepts through in-and-out boxes.
