Well, that question sure is.

But seriously, certain areas of math are quite ambiguous. The Banach-Tarski paradox describes how, using current mathematical practices, one can prove that it is possible to take a sphere with volume x, cut it up into a finite number of pieces, and reassemble those pieces into two spheres, both with a volume of x.

Right... What kind of "truth" is that?

To be fair, though, when I made my comment about language being ambiguous, I wasn't really referring to the language of mathematics.
