Well, the function contains three forms where the results of the first
two are ignored and only the value of the last one is returned. So here
you need an `if`.
(defn abs [x]
(if (< x 0)
(* x -1)
x))

BTW: Why do you have those semicolons in your code? That ends a
statement in C-like languages but in Lisps including Clojure it starts a
comment spanning till the end of the line.
