Mathematical philosophy is all about looking at the world around us and trying to see it through a mathematical lens. It's about trying to use math to answer questions about how the world works, why people do the things they do, and how we can measure things better. This means that philosophers might study things like geography, economics, numbers, patterns, and more - anything that has to do with the way people think and act. In particular, mathematical philosophy looks at how math can explain the world, and how it can help us understand the big ideas about life.
