The hotel is fully booked  the rooms are full of Numbers  both Odds and Evens  yet guests continue to arrive. When Zero shows up  theres a massive room switching  and he stays  even though Mr. Hilbert insists hes not really a Number. Then the Letters appear and everyone still has a room  even though no Numbers have left. No matter how many guests arrive or depart  the hotel accommodates them all  and is always full. But when the Fractions arrive  demanding rooms  real chaos threatens. Can an ingenious solution be found to house them all?  Based on mathematician David Hilberts famous paradox of the Grand Hotel  The Cat in Numberland offers a refreshingly clear explanation of infinity for readers of all ages. John OBriens imaginative line drawings further elucidate the complex concept  as well as simple functions like addition  subtraction  division  and multiplication.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":44945334009909,"sku":"ByrdShop_081262744X","price":100.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780812627442_76c2ec3c-f4f1-48e5-bc82-a298251ad55a.jpg?v=1770138285","url":"https:\/\/atxbooks.com\/products\/the-cat-in-numberland","provider":"ATX Books","version":"1.0","type":"link"}
