Since 5,\( 404 ; 4,533 ; 5,561 \); and 5,481 are all about the same size, about how large is their sum? Explain briefly. Use the Show Work feature to provide related calculations and additional reasoning to your answer. The sum is about \( \square \).

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!
