What the Reviewers Say

“Brilliant. . . . Where Fernandez’s book scores highly is that it goes beyond being a typical self-help manual for the numerate, by presenting example after example of how mathematical topics such as probability, game theory and exponential functions really do make sense of a world that can sometimes seem so subjective. It’s also an easy-going analysis of those areas in life that get brushed under the carpet, to be attended to another day. Once you realise it all boils down to maths, you will wake up happier, wealthier and healthier tomorrow morning, and we have Oscar E. Fernandez to thank for that.” Nick Smith, Engineering & Technology (full review here)

“With an informal, engaging tone and sound applications, The Calculus of Happiness facilitates financial literacy. This is the first time I’ve encountered a book aimed at general readers that addresses the topic of financial mathematics. It is a valuable work that will serve as a lifelong resource.”–John A. Adam, author of A Mathematical Nature Walk

“I absolutely love this book. The mathematics described is beautiful and accessible and, most important of all, truly meaningful and relevant.”–James Tanton, author of Without Words: Mathematical Puzzles to Confound and Delight

“With its appealing informal style, choice of topics inspired by everyday life, and links to the relevant mathematical concepts and methods, this book shows how mathematics can improve one’s quality of life. From healthy eating to managing the monthly budget, readers will look at their daily activities from an angle they may have never thought of.”–Max Alekseyev, The George Washington University

“[E]ngaging. . . . Readers are sure to get a sense of how content from algebra and precalculus can help inform us about important decisions that are almost universally relevant.”–Jason M. Graham, MAA Reviews (full review here)
