Answer
The sum is about 21,000.
Solution
1. First, round each number to the nearest hundred:
- \( 5,\!404 \) rounds to approximately \( 5,\!400 \).
- \( 4,\!533 \) rounds to approximately \( 4,\!500 \).
- \( 5,\!561 \) rounds to approximately \( 5,\!600 \).
- \( 5,\!481 \) rounds to approximately \( 5,\!500 \).
2. Next, add the rounded numbers:
\[
5,\!400 + 4,\!500 + 5,\!600 + 5,\!500 = 21,\!000
\]
3. Therefore, the sum is about \( 21,\!000 \).
The sum is about \( \boxed{21,\!000} \).

Simplify this solution Bonus Knowledge
To estimate the sum of the numbers, we can round them to the nearest thousand for simplicity: - 5,404 rounds to 5,000 - 4,533 rounds to 5,000 - 5,561 rounds to 6,000 - 5,481 rounds to 5,000 Now adding those rounded values together gives: 5,000 + 5,000 + 6,000 + 5,000 = 21,000 So, the sum is about 21,000. This method of rounding helps in quickly estimating sums without getting bogged down by exact figures! Keep in mind that rounding can make a difference when dealing with precise calculations, but for estimation purposes, this approach saves time and provides a solid approximation!
