The Magic Function Machine is an interactive, gamified single-file HTML web application designed to demystify one of the most foundational concepts in algebra: the function.

Students feed "raw numbers" into the top of the machine, watch the gears churn, and observe the "wrapped candy numbers" that emerge from the conveyor belt below. B
