  3. Mathematical problem - Wikipedia

    en.wikipedia.org/wiki/Mathematical_problem

    Known as word problems, they are used in mathematics education to teach students to connect real-world situations to the abstract language of mathematics. In general, to use mathematics for solving a real-world problem, the first step is to construct a mathematical model of the problem. This involves abstraction from the details of the problem ...

    One such component is the emotional valence of "real-world" problems, which can either impede or aid problem-solving performance. Researchers have focused on the role of emotions in problem solving, [ 11 ] demonstrating that poor emotional control can disrupt focus on the target task, impede problem resolution, and lead to negative outcomes ...

    TFT is a common strategy in real-world social dilemmas because it is nice but firm. Consider, for instance, that marriage contracts, rental agreements, and international trade policies all use TFT-tactics. However, TFT is quite an unforgiving strategy, and in noisy real-world dilemmas a more forgiving strategy has its own advantages.
