Robin Hood Math

How the rich and powerful use math to exploit you, and what you can do to beat them at their own game

Everything we do today is recorded as data that's sold to the highest bidder. Plugging our personal data into impersonal algorithms has made government agencies more efficient and tech companies more profitable. But all this comes at a price. It's easy to feel like an insignificant number in a world of number-crunchers who care more about their bottom line than your humanity. It's time to flip the equation, turning math into an empowering tool for the rest of us.

Award-winning mathematician Noah Giansiracusa explains how the tech giants and financial institutions use formulas to get ahead-and how anyone can use these same formulas in our everyday lives. You'll learn how to handle risk rationally, make better investments, take control of your social media, and reclaim agency over the decisions you make each day.

In a society that all too often takes from the poor and gives to the rich, math can be a vital democratizing force. Robin Hood Math helps you to think for yourself, act in your own best interests, and thrive.
