You can run the file interactively by typing `python3 -i` and call the functions on some of your own tree examples. Slides 23-25 describe how you can create your own trees.

Having trouble counting the number of calls to calc_eval and calc_apply? Run ‘python -i’ inside the folder that holds the file.
Now you can run calc_eval and calc_apply on pairs that you want to create. There are print statements inside these functions that will let you see the order that they are evaluated / applied in!

ex. p1 and p2 are both already defined inside the file
>>> calc_eval(p1)
