`(let* ((p1 '(1 2 3 4 5 6))` |
| - | |
Variable `p1` is a List of 6 integers |

`1111111(p2 (list-ref p1 2))` |
| - | |
`p2` is 3 (show the third element starting the count at 1) |

`1111111(p3 (cddr p1))` |
| - | |
`p3` is `'(3 4 5 6)` (first two elements removed) |

`1111111(p4 (list (car p1) (cadr p1)))` |
| - | |
`p4` is `'(1 2)` (all but first two elements removed) |

`1111111(p5 (last p1))` |
| - | |
`p5` is `6` (all but first two elements removed) |

`1111111(p6 (cons -2 p1))` |
| - | |
`p6` is `'(-2 1 2 3 4 5 6)` (-2 placed at head of list) |

`1111111(p7 (cons '(1) '((2) (3) (4))))` |
| - | |
`p7` is `'((1) (2) (3) (4))` (objects in list can be anything) |

`1111111(p8 (append '(1) '(2 3 4 5))))` |
| - | |
`p8` is `'(1 2 3 4 5)` (append the list `'(2 3 4 5)` to `'(1)`) |

`111(list p1 p2 p3 p4 p5 p6 p7 p8))` |
