About this item
Elementary students around the globe are taught to count using a base-10 number system. We form numbers using the 10 digits of our base-10 systemzero through nine. Inside this book, readers discover other number systems people have used throughout history. With a binary system, computers only use two digits0 and 1. So how does a computer count to 10? Readers will learn the answer inside this book. Also included is a review of hexadecimal numbers, which serve as the old basis of assembly languages and can still be found today setting colors on the web. This volume meets math standards addressing number systems other than base 10.
About the Author
A former arts administrator who handled funding for literature, theater, dance, and the visual arts, Patricia Harris has written about travel, food, art, and popular culture since she stopped going to other people's offices in the 1990s. She is co-author with David Lyon of more than thirty books that range from travel guides to one volume that plumbs the symbolism and semiotics of food. She is also the sole author (and photographer) of "100 Places in Spain Every Woman Should Go." In addition to books, she and David Lyon travel the world--and their home region of New England, for that matter--writing for magazines, newspapers, and web sites about interesting places and people and good things to eat. Although she shares the same name, she has never been the Secretary of Housing and Urban Development and knows nothing about teaching children how to write software. She and David Lyon live in Cambridge, Massachusetts, and make their online home at www.HungryTravelers.com.
