The question asks for the value of $|9|$. The vertical bars represent the absolute value, which is the distance a number is from zero on the number line, without considering the direction (always non-negative).

So, $|9|$ is simply:

$|9| = 9$

Would you like further details on this concept, or have any questions?

Here are 5 related questions to deepen your understanding:

1. What is the absolute value of $-9$?
2. How would you calculate $|0|$?
3. What is the absolute value of a negative decimal like $-3.5$?
4. How does the absolute value function affect variables in algebraic expressions?
5. Can absolute values ever be negative?

Tip: Absolute values always return non-negative results, regardless of whether the original number is positive or negative.
