Numbersight: A Street-Fighting Mathematician Teaches How to Make Better Decisions

The world constantly asks us to decide. And many of these decisions turn on the ability to use numbers to size up situations quickly.

Numbersight teaches you how to make sense of the world by connecting, organizing, and simplifying the numbers that describe it. You will learn to build rich structures of meaning while leaving mental room to think and decide (without getting your mind gummed up with useless information).

I have been sharpening these reasoning tools for over 15 years, in teaching them around the world, including at MIT, Cambridge University, and Olin College. I have taught them to some of the world's leading analysts and management consultants. With these tools, you can make numbers meaningful so that they work for you: so that they help you understand and be more effective in the world around you.
