Someone else on the list might go about this differently, but I'll ask
you this question to start:

If I write

(define (my-add a b)
  (+ a b))

and then write

(my-add 3 5)

What syntactic position does "my-add" occupy? Now, couple that with
the documentation for "build-vector" and see if that doesn't get you a
bit unstuck.
