If memories of learning algebra bring you out in a cold sweat and thoughts of quadratic equations cause you feelings of fear and dread, I Used to Know That: Maths can help. A light-hearted and informative reminder of the things that we learnt in school but have since become relegated to the backs of our minds, this book will help you to brush up on your mental arithmetic, including percentages, averages and recurring decimals or work on your trigonometry skills, from Pythagoras' theorem to triangle areas and angles. It can be used a practical guide to turn to when an answer is eluding you, from helping a child with homework to calculating change or understanding statistics. I Used to Know That: Maths is a fun and accessible way to re-visit all those useful tips and maths tricks that you have forgotten from your school days.

Let the real world show you how maths works.Maths is often cited as the ‘most difficult’ or ‘complex’ subject to study, many people admitting to a wariness that was probably ingrained into them in their schooldays. In Maths in Bite-sized Chunks, Chris Waring proves that it’s easy to break the subject down into accessible, understandable information, much of which, in fact, we use in one way or another every day of our lives.Each chapter takes readers through the theory, demonstrating how to master it with worked-through problems and examples from the real world. Topics that once seemed impenetrable suddenly become relatable and easier to unpick. So whether it’s algebra or statistics that once had you flummoxed, get ready for a new way of being mathematically minded.

Whether you paid much attention to the mathematics you were taught at school or not, the inescapable truth is that one day, an equation could just save your life.The real world is full of equations and a lot of our everyday decisions are calculated – we just don’t always realize it. And that’s ok – you unthinkingly use differentiation when you’re crossing the road between traffic and you will pretty much always make it to the other side safely. But what if you were plummeting to your death in a plane with no engine and you needed to know what size parachute to make from your cabinmate’s sari in order to jump and survive? Or you were in charge of pinpointing the origins of an important message from outer space? These entirely plausible real-life situations clearly require a little more thought. From how to work out the best guard configuration to protect a world-famous painting in the Louvre to saving the planet from total blackout during an energy crisis, Chris Waring demonstrates the mind-bending and humanity-saving beauty of equations.

Mathmatters is a humorous guide to the hidden calculations that are essential to everything we do.From making a cup of coffee to negotiating traffic to selecting candidates for an interview, we can’t make it through the day without employing some essential mathematics. Did you know that there are some serious calculations involved in making the perfect cup of coffee (involving ratios)? That an understanding of Braess's paradox will mean you can remain calm about road closures on your commute as they may make your journey faster (using equations relating to speed/distance/time)? Or that your online shopping habit can teach you about game theory (mathematical models of strategies)? Full of easy-to-understand mathematics and fun, if not entirely helpful, illustrations, Mathmatters is your essential guide to understanding the rules and measures that surround us every day, and determine the outcome of every move we make, every button we press and much of our decision-making, whether we are aware of it or not.

We may remember their equations and discoveries from school, but do we remember who the men behind the maths were? From the theories of Pythagoras (did you know he ran a secret brotherhood that studied maths, music and gymnastics?) to coining the term 'Googol', From 0 to Infinity in 26 Centuries: The extraordinary story of maths is packed full of fascinating facts and surprising stories from ancient times to the modern day.Do you want to know why the Ancient Greeks knew so much maths? Or, why there was so little maths studied in the Dark Ages? Read this fascinating book to uncover the mysteries of maths...
