'The perfect introduction to the power of mathematics - fluent, friendly and practical.'-Tim Harford, author of How To Make The World Add Up

'Numbercrunch is a lucid, and, most importantly, entertaining, guide to the mathematics that forms the plumbing of the modern world. With barely an equation in sight, he makes a passionate case for how just a little bit more numeracy could help us all.'-Tom Whipple, Science Editor, The Times


'An excellent, straightforward introduction to the usefulness of numbers, which gets to the heart of why maths is so important to all for us.'- David Sumpter, author of The Ten Equations That Rule the World


'Numbercrunch is an invaluable addition to the modern baloney detection kit. Numbers don't lie but they often speak a foreign language. Professor Oliver Johnson is a superb maths-whisperer on a mission to arm his readers with the tools to distinguish sound claims from the many phoney ones that bombard us every day. Numbercrunch is an invaluable addition to the modern baloney detection kit.'-Ananyo Bhattacharya, author of The Man from the Future: The Visionary Life of John von Neumann


'Oliver Johnson provides useful and timely insights by deploying simple but powerful mathematical techniques. Numbercrunch shows how to apply crucial ideas to a range of real-life problems. A valuable and topical guide to navigating the world of numbers, from sports transfers to medical testing.'-Adam Kucharski, author of The Rules of Contagion: Why Things Spread
