👉 Builders' math, also known as game theory, is a branch of mathematics that studies strategic decision-making in situations where the outcome depends on the actions of multiple individuals or entities. It involves analyzing how rational actors will behave to maximize their own benefits, often leading to outcomes that are not necessarily optimal for any single participant. Key concepts include Nash equilibrium, where no player can benefit by changing their strategy while others keep theirs unchanged, and the prisoner's dilemma, which illustrates how individual rationality can lead to suboptimal collective outcomes. Builders' math is widely applied in economics, political science, sociology, and computer science to model and predict strategic interactions and outcomes.
