Math City is a place where is into Math book, and also the pages of the book are the streets of Math City.
In this City, Monster Number was grossly overweight and had a shaggy body, like a mammoth. In the beginning, Monster Number could not walk very well. Though he swayed a little, tottering and often falling, my father trained him for detecting and killing. After a few days, we attacked Math City.
Math City was bombarded, the doors and the walls shaking while the dark shade of the Monster Number came down, covering the city. Monster Number threw big stones, one after another; and like a repulsive ghoul crashed through any barrier.
Then, after many horrible explosions, Monster Number entered the city, and we followed him. He smashed countless numbers as he put down his steps on the earth.
