TITLE: What does $\frac{x^3}{9}\bigg|_0^1$ mean, and how should it be spoken?
QUESTION [9 upvotes]: $$\frac{x^3}{9}\Bigg|_0^1$$
The vertical line above: what does it mean, and how would I state this whole structure in spoken words, so that a screen reader would be able to read it aloud correctly?

REPLY [5 votes]: It looks like people have already told you what to do mathematically. I'm a math tutor, and what I say out loud is 

"x cubed over nine, evaluated from one to zero."
