Life. Mathematics as a Way to Be Happier and Live Longer

«Just like love and music, mathematics has the gift of making people happy,» — posits the author, German mathematician Christian Hesse.
Do you want your marriage to be happier? Just use the formula 5:1. Do you wish to extend your life... or fairly share a cake? Win the lottery? Make a smart bet? Learn to predict the future? That's not a problem. The author introduces simple rules that easily compensate for complex analysis and quickly lead to correct decisions. Having mastered 31 chapters of this book, you will learn an introductory practical course of mathematical wisdom that will help you live anew.
Mathematics is not just a grand mental experiment, but also a tool developed alongside ancient human culture, which should always be kept at hand. Heating works, planes fly, bridges stand, only when the calculations are correct. However, this universal science is capable of solving quite everyday problems, as you will come to realize.
