For many of us, mathematics is a subject to be feared— a daunting world of schoolroom numbers and equations. Yet we often wish in everyday life that we could remember all those handy mathematical tools and tips that were once explained to us— Maths Squared provides the bite-sized solution. Everybody knows and understands Pythagoras’ theorem and pi, but Maths Squared introduces you to the world of Einstein’ s relativity theory, Euclidean geometry, and the butterfly effect. 

Maths Squared is an ideal reintroduction to the mysterious and magical world of numbers. Across 10 chapters and 100 topics, it takes you on a whistlestop tour from the essentials of numbers and arithmetic to the strange outer limits where mathematics and philosophy merge. Along the way, it looks at many of the key problems that have led to mathematical breakthroughs, and some of those which remain unsolved.

Using accessible yet authoritative text complimented by new color illustrations, infographics and photographs, Maths Squared is the ideal primer or refresher for those who want to learn more about the fascinating language of numbers and equations that describes the Universe.
