Can a group of friends cut up a cake, so that no one is envious of someone else's portion? Can three people who’ve just leased a three-bedroom apartment assign rooms and rent, so that no one feels like someone else has gotten a better deal? These questions have many hard-to-quantify factors. Learn an envy-free division process that’s easy to implement, and answers these and many related questions.
