`(disivible '(1 2 3 4 5 6 7)).This is what I've made so far:

```
(defun divisible(n)
    (cond ((eq n 0) nill) (eq(rem n 3) 0) t )('else 0)))

```

But I'm new in lisp and I don't know how to make it not show me the numbers divisible by 3 but just add the numbers and show me in result. Can someone help me please?
