Methods (also called functions) are reusable blocks of code. They help organize your program and avoid repetition.
🛠️ Defining a Method

🎯 Why Use Methods?
- Reusability: Write once, use many times.
- Organization: Break big problems into smaller pieces.
- Debugging: Easier to find and fix bugs.
📝 Try It!
Write a method that multiplies two numbers and returns the result.

| int Multiply(int x, int y)
{
return x * y;
}
Console.WriteLine(Multiply(4, 5)); // 20
