# High School Math 3B

## How can I use math to explain my world?

### Why Take This Course?

Algebra is like arithmetic, but with variables instead of numbers. That means that you already know most of the concepts of Math 3B on a fundamental level. Mastering algebra is just a matter of extending those fundamental concepts to a more abstract level. Learning to notice patterns and structure in simple situations and extend them to more abstract situations is something that can be used in all areas of life. Algebra trains the brain to think logically, and it teaches a whole new way of looking at the world. In Math 3B, we will explore the idea of functions in more depth and model real world situations with geometry, sinusoidal functions, and statistics.
