Optimization problems are all about finding the best solution in real-world scenarios. From maximizing profits to minimizing costs, these problems use math to make smart decisions. You'll learn to identify key variables, set up , and solve for optimal outcomes.
focuses on shapes and sizes. Whether you're designing a garden or a shipping container, you'll use formulas to maximize area or volume. The key is understanding how different dimensions relate and finding the perfect balance for your goals.
