I got sucked at the second part. I have already assigned difference as a constant and the code compiles nicely in Xcode but I still can't get through this assignment. Can someone help? Sorry.
/**
For this code challenge, let’s define a math operation as a function that
carries out some work on two integers and returns an integer as well. An
example is the function below, `differenceBetweenNumbers`, which takes two
integers and calculates the difference between the numbers. After calculating,
it returns the difference.
*/
func differenceBetweenNumbers(a: Int, b:Int) -> (Int) {
return a - b
}
// Enter your code below
func mathOperation (differenceBetweenNumbers:(Int, Int) -> Int, a: Int, b: Int) -> (Int){
return differenceBetweenNumbers (a, b)
}
let difference = mathOperation(differenceBetweenNumbers, 1, 2)

16,009 PointsYou shouldn't have the differenceBetweenNumbers function inside the parameter for your mathOperation function. Try this instead:
func mathOperation(a: Int, b:Int) -> (Int) {
return a + b // This can be any operation: +, -, /
}
And remove the last statement, since the instructions don't ask you to create a variable with your function.
Hope this helps!

Courses Plus Student 2,601 PointsSorry the question to the second part is as below:
"Using the differenceBetweenNumbers function as an input to mathOperation, compute the difference between any two integers and assign the result to a constant named difference."
That was why I assigned the constant difference.
