## What do you learn in Introduction to Mathematical Economics

Mathematical Economics blends economic theory with mathematical models. You'll learn to apply calculus, linear algebra, and optimization techniques to economic problems. The course covers utility theory, production functions, market equilibrium, and game theory. You'll also dive into econometrics, using stats to analyze economic data and make predictions.

## Is Introduction to Mathematical Economics hard?

It's no walk in the park, but it's not impossible either. The math can be pretty intense, especially if you're not a math whiz. Concepts like partial derivatives and Lagrange multipliers might make your head spin at first. But if you've got a solid foundation in calculus and some basic econ knowledge, you'll manage. Just be ready to put in the work.
