This question makes no sense to me. I don't understand what it means by external names

What do i do from here?

// Enter your code below
func getRemainder(a: Int, b: Int) -> Int {
 return a % b

The external name is in this case what comes before a and b in the input of the function. You usually use the external name to explain what kind of input the function wants, the internal name is usually simpler and shorter and is only available inside the function. You separate the internal and external names with a space. Hope this helps.
