## What do you learn in Computational Mathematics

Computational Mathematics blends math with computer science to solve complex problems. You'll learn numerical methods, algorithm design, and data structures. The course covers topics like linear algebra, optimization, and differential equations, but with a focus on implementing these concepts using programming languages. You'll also dive into machine learning basics and scientific computing.

## Is Computational Mathematics hard?

Computational Mathematics can be challenging, especially if you're not comfortable with programming. It requires a solid foundation in math and the ability to think algorithmically. The course can be math-heavy, which some students find tough. But if you enjoy problem-solving and have a knack for coding, you might find it more manageable and even fun.
