"... an enjoyable useful book...that helps the reader better interpret and engage with the numbers around them. I enjoyed reading it, and learned from it." -- Francis Hunt, The Mathematical Gazette

Is That a Big Number? is an easy but excellent read for the person who wants to understand large numbers in context of everyday life ... A key tenet of this book is the idea of comparison: every example is stacked against a well-known fact. Every chapter ends with a list of (approximate) relations to help the reader grasp magnitudes of heights, distances, weights, and riches." -- Megan Sawyer, Mathematical Association of America

"The book illustrates well that knowledge (being numerate) is power." -- Adhemar Bultheel, European Mathematical Society

"Wide-ranging and highly accessible, this book is chock-full of fascinating nuggets, providing a rich source of colourful examples of numbers and how they are used. It shows how numeracy and literacy are two sides of the same coin." -- David J. Hand, Senior Research Investigator and Emeritus Professor of Mathematics at Imperial College, London

"This book explores mathematics in a way I have never thought about before. Elliott offers explanations to mathematical ideas in new ways and made them much easier for me to understand." -- Jamie A. Griffin, Yale National Initiative

Impressive statistics are thrown at us every day - the cost of health care; the size of an earthquake; the distance to the nearest star; the number of giraffes in the world.

We know all these numbers are important - some more than others - and it's vaguely unsettling when we don't really have a clear sense of how remarkable or how ordinary they are. How do we work out what these figures actually mean? Are they significant, should we be worried, or excited, or impressed? How big is big, how small is small?

With this entertaining and engaging book, help is at hand. Andrew Elliott gives us the tips and tools to make sense of numbers, to get a sense of proportion, to decipher what matters. It is a celebration of a numerate way of understanding the world. It shows how number skills help us to understand the everyday world close at hand, and how the same skills can be stretched to demystify the bigger numbers that we find in the wider contexts of science, politics, and the universe.

Entertaining, full of practical examples, and memorable concepts, Is That A Big Number? renews our relationship with figures. If numbers are the musical notes with which the symphony of the universe is written, and you're struggling to hear the tune, then this is the book to get you humming again.
