Zero the Hero

Zero. Zip. Zilch. Nada. That''s what all the other numbers think of Zero. He doesn''t add anything in addition. He''s of no use in division. And don''t even ask what he does in multiplication. (Hint: Poof!) But Zero knows he''s worth a lot, and when the other numbers get into trouble, he swoops in to prove that his talents are innumerable.
