[Haskell-cafe] Printing the function result

Hi, I am going through examples from the textbook and trying them out but some don't work. For example: addNum :: Int -> (Int -> Int) addNum n = addN where addN m = n+m This error message i am getting: ERROR - Cannot find "show" function for: *** Expression : addNum 4 *** Of type : Int -> Int Now, the type of show is a->String, but i need some kind of function to print the function as a result. I tried some input output functions but i don't think that is the right way to follow. Can anyone suggest me where to look?
