Poetry: Divide by Zero

Note: I can't find if there's a minimum word limit to this.

When dividing by zero,
you put a bar or line over zero.
This bar over zero
is like a teeter totter.
Rock the sides up and down,
the slope tries to approach the answer.
The actual answer to dividing by zero is the slope of the bar
when it's fallen off and leaning on the zero vertically.
Which side you ask?
It could be either.
So is it negative or positive?
You tell me.
