The expression you've written, \( \frac{n}{n-2!} \), contains a factorial. Let's break it down:

1. **Factorial**: The factorial of a number \( x \), denoted \( x! \), is the product of all positive integers up to \( x \). For example:
   - \( 2! = 2 \times 1 = 2 \)

2. **Expression**: You are dividing \( n \) by \( n - 2! \), which simplifies to:
   \[
   \frac{n}{n - 2!} = \frac{n}{n - 2}
   \]

This means the expression simplifies to \( \frac{n}{n - 2} \), where the factorial \( 2! = 2 \).

Let me know if you'd like more details, or if this clears things up! Here are five related questions for further exploration:

1. What is the result of \( \frac{n}{n - k!} \) for different values of \( k \)?
2. How do you compute larger factorials, such as \( 5! \) or \( 7! \)?
3. What happens if \( n = 2 \) in your original expression?
4. How can you apply factorials in probability problems?
5. How does the factorial function behave as \( n \) approaches infinity?

**Tip**: When using factorials, always ensure that the input is a non-negative integer, as the factorial function is only defined for such numbers.
