volume_mute
Round each number to the nearest hundred and estimate the value of the expression:
\[-5{,}684 + (-2{,}270) + 3{,}404 + 2{,}689\]
Correct Answer
\(-1{,}861\)
Explanation
Round: \(-5{,}684 \to -5{,}700\), \(-2{,}270 \to -2{,}300\), \(3{,}404 \to 3{,}400\), \(2{,}689 \to 2{,}700\).
Positives: \(3{,}400 + 2{,}700 = 6{,}100\). Negatives: \(-5{,}700 + (-2{,}300) = -8{,}000\). Net: \(6{,}100 + (-8{,}000) = -1{,}900\). Closest listed answer: \(-1{,}900\).
