That is not a macro.  That's a function.  The return value of a macro
(the result of the last expression in the implicit progn) needs to be a
(quasi-)quoted expression.

This macro simply evaluates to 42.  This should be a function.

If you want a macro, you could have:

#+BEGIN_SRC: emacs-lisp
  (defmacro forty-two ()
            '(* 6 7))
#+END_SRC

For what you want, you could have it be:

#+BEGIN_SRC: emacs-lisp
  (defmacro forty-two ()
            `,(* 6 7))
#+END_SRC


[...]
