They asked for
- a function called “mathOperation”
- Two variables of Int type
- a return type of Int
- and to return the result of a math function with those integers.
Where did i go wrong
func mathOperation (a: Int, b: Int) -> (Int) {
return a + b
}

"Write a function called mathOperation that takes a math operation (as defined in the editor) as the first input, two integers on which we carry out the math operation, and a return type of Int. The body of the function simply returns the result of the math operation you pass in. Note: We are attempting to build a higher order function so your first parameter must be a function. If you're having trouble, read the Function Types as Parameter Types section in the docs"
See that? Your first parameter must be a function. mathOperation should have three parameters. Instead of picking a random math operation to perform on the two integers, you should use the function supplied as the first parameter. An example of this is in the linked documentation if you're having trouble!
