The number "absolute value of (3-pi)" is equal to:
3-pi
pi-3
pi+3
-3-pi
9-pi^2

Totally confusing!

Do you know the value of $\pi$?
Do you know $| \pi - 3| =|3 - \pi|>0$?
So which?

We know the absolute value will give us a positive answer.

$|3-\pi|=|-.14159...|=.14159....=\boxed{\pi-3}$

That's the only one that works.
