stops :: int->int->int

I think that says that the function stops takes two integers and returns an integer.

This is correct (though as someone else pointed out, Haskell types start with a capital letter).

What i'm not entirely sure of is how i'd then write the function itself because i literally want it to have the following form

stops (x,y) = x+y

As "stops" just adds numbers, it is equivalent to the + operator, so you don't have to write a function at all. It doesn't do any harm to write a function, but the simplest way of expressing "stops" is this: stops :: Int -> Int -> Int stops = (+) One of the benefits of a functional language is that you can assign functions as well as data!
