Solve Absolute Value Expression: |5 - 9| Calculation

$|5 - 9| =$

To solve this problem, we will follow these steps:

• Evaluate the arithmetic expression inside the absolute value symbol.
• Apply the definition of absolute value to determine the result.

Now, let's work through each step:
Step 1: Evaluate the expression $5 - 9$.
- To find $5 - 9$, we subtract 9 from 5, which gives us $-4$.

Step 2: Apply the absolute value.
- The absolute value of a number is its non-negative value. Since $-4$ is negative, we take the opposite: $|-4| = 4$.

Therefore, the absolute value of $5 - 9$ is $4$.
