(CAR ’((/ 1 2.2) -80.2 -23.002 (* 2 3.3))) devuelve (/ 1 2.2)
(CAR ’(34.45 décimo -12)) devuelve 34.45
(CAR ’(x y z)) devuelve X
(CAR ’(3)) devuelve 3

(CDR ’(8 80.01 -23.4 23 34.67 12)) devuelve (80.01 -23.4 23 34.67 12)
(CDR ’(x y z)) devuelve (Y Z)
(CDR (CAR ’((1 2 4) (3 5 7) (8 1 2)))) devuelve (2 4)

(CADR ’(10 20 34)) devuelve 20
(CADR ’(23 -2 1 34 56.0 (+ 2 2))) devuelve -2
(CADR ’(19 21)) devuelve 21
(CADR ’(21)) devuelve nil
(CADR ’()) devuelve nil
