volume_mute
Round each number to the nearest hundred and estimate the value of the expression:
\[-3{,}887 + (-5{,}806) + 4{,}701\]
Correct Answer
\(-5{,}000\)
Explanation
Round: \(-3{,}887 \to -3{,}900\), \(-5{,}806 \to -5{,}800\), \(4{,}701 \to 4{,}700\).
Positives: \(4{,}700\). Negatives: \(-3{,}900 + (-5{,}800) = -9{,}700\). Net: \(4{,}700 + (-9{,}700) = -5{,}000\).
