There is Math City, where is into Math book and also the pages of book are the streets of Math City. The meeting and negotiation ended before they arrive to a peaceful solution. Warning: To all dear numbers of the city: Beware a minus, called Lying Line, and is prowling about. Stay away from him! You will change to zero if he should find you! Oh yes, being zero is equal to your death. This minus is armed with cold and hot weapons to include a sharp knife and a loaded gun! The Lying Line saw his picture on the warning. He was embarrassed and continued sadly on his way.
