Function operations are really important as students get ready for calculus. Here’s how they help:

1. Understanding Relationships: When you add or multiply functions, you're discovering how different functions work together. This is very important in calculus, where mixing functions happens a lot.

2. Foundational Skills: Working with expressions like $(f + g)(x)$ or $(f \cdot g)(x)$ helps you practice. This builds a strong base for the more complex rules you'll face in calculus.

3. Graphing Insights: Learning to work with functions also helps you draw graphs. This is a big part of calculus! Knowing how changes in a function affect the graph is key to understanding limits and derivatives.

In summary, getting good at these operations makes calculus concepts much easier to understand!
