Hi Mohammad

In this challenge, the tricky part can be the return: you have to specify the return type in the function and return the result of the math operation:

func getRemainder(value a: Int, divisor b: Int) -> Int { // The return type is specified here: -> Int
     let result = a % b //The constant is simply used to assign the result of the math operation to it and then return it below.
     return result
}

getRemainder(value:10,divisor:3) //Here, notice you need to use the external parameter names when calling the function.

I hope that helps! :-)
