Mathmatters is a short-read that tells us about the math hidden calculations behind our everyday life.
I bought this book from the London science museum and I'll admit, I was very skeptical about it, until I've read and I've actually enjoyed learning the calculations done throughout the book that included simple mathematics.
I recommend this book for people who are fond of math with a highschool level knowledge of it. It only took 2 days for me to complete it so I can promise you it won't feel like a complete waste of time.
