ELI5: Explain Like I'm 5

Mathematical model

A mathematical model is like a way of looking at the world that uses numbers and equations to explain how things behave. It's like a map or a recipe that helps us understand how different things work together. For example, a mathematical model can help us understand how air pollution affects our health. It can also help us figure out things like the best way to build a bridge. In school, mathematical models can help us find the answers to math problems.
