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

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!
