At Mr. and Mrs. Hilbert’s Hotel Infinity, the resident cat is puzzled. The hotel is fully booked the rooms are full of Numbers, both Odds and Evens yet guests continue to arrive. When Zero shows up, there’s a massive room switching, and he stays, even though Mr. Hilbert insists he’s 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 Hilbert’s famous paradox of the Grand Hotel, The Cat in Numberland offers a refreshingly clear explanation of infinity for readers of all ages. John O’Brien’s imaginative line drawings further elucidate the complex concept, as well as simple functions like addition, subtraction, division, and multiplication.

From School Library Journal:

Grade 3-5–In this clever tale, Mr. and Mrs. Hilbert are the proprietors of the Hotel Infinity, an establishment for Numbers of all sizes. The odds and evens live happily together, playing games like addition and subtraction until Zero comes to call. Mr. H refuses to admit him on the grounds that, Zero is not a Number...Numbers serve to count things. His wife disagrees, and she offers 10, 100, and 1000 as cases in point. Defeated, her husband agrees to give him a room, but which one? The hotel is fully occupied. Zero suggests each guest move up one. Everyone is happy but the cat, who ponders how a hotel that was already full could suddenly accommodate another guest. Zero tells the others about a place called Alphabet where the Letters live. They cannot play the games we know, but they know others that are very interesting.... When they invite the Letters for a sleepover, Zero proposes that he move to Room 26, and the others follow suit. Again, the cat cannot fathom where all these extra rooms have come from. In the end, the Hotel Infinity becomes famous far and wide as it is always full, yet there is always room. The clever black-line and crosshatch sketches portray the number and letter people as comical aliens. Readers will particularly enjoy poring over the scenes of the numbers at play as they search for recognizable patterns and number sentences. This easy chapter book explains concepts such as odd and even, the four operations, fractions, patterns, algebra, and infinity. More importantly, it presents a difficult, sometimes-feared subject, in a fun, lighthearted way.–Barbara Auerbach, New York City Public Schools
