Limits can be a tough topic in pre-calculus, and many students find them confusing. They deal with how functions act as they get close to a certain number. This idea can be tricky to get.

Why Limits Can Be Hard:

• Hard to Picture: Limits are often very abstract, which makes them tough to visualize.
• Complicated Symbols: The math symbols and phrases, like $f(x) \to L$ as $x \to a$, can feel overwhelming.
• Different Types of Functions: Understanding the difference between continuous and discontinuous functions adds to the confusion.

How to Improve Understanding:

• Practice: Working through different limit problems can help you get better at understanding them.
• Visual Aids: Using graphs of functions can make the idea of limits clearer.
• Ask for Help: Studying with others or getting a tutor can give you the support you need.
