I am learning LISP by Emacs. I made two lists: List1

I am learning LISP by Emacs.

I made two lists: List1 and List2.

I must use mapcar and lambda for List1 minus List2 and store the outcome in one list such as (3 2 1)

Why did I get three different lists? Can you help me fix the code?

Thank you
