If I can run part of this, maybe you can see it.

Okay, she's pushing a little blue arrow, a little play button.

So basically, if I run this code, you will see the results.

Oh, a little box appeared in a different window.

Yes.

So if you check the numbers, minus 18.11432, and I'm looking at the published version, it says minus 18.114 star, star, star.
