Can you clarify what you're asking a bit? You ask about what a module is, but your code implies that you mean that you're wondering what the modulo operator (%) does, and these are 2 entirely disparate and unrelated concepts in Swift

The modulo operator (technically called the remainder operator in Swift) was covered in the Arithmetic Operators video back in the Swift Basics course.

But to offer a quick recap, it looks like the percentage symbol % and gives you the remainder of dividing two numbers. So 4 % 3 for example would result in 1.

All you need to change in your code to pass the task is to replace the / symbol with %.
