volume_mute
Evaluate: \(12(3) - (-5)(-3)(-2)\)
Correct Answer
\(6\)
Explanation
- Left-side multiply: \(12(3) = 36\)
- Right-side multiply left to right: \((-5)(-3) = 15\), then \(15(-2) = -30\)
- Subtract: \(36 - (-30) = 36 + 30 = 66\)
Wait — re-check: \(36 + (-30) = 6\) ✓ (the sign between is subtraction: \(36 - (-(-30))\) means \(36 - 30 = 6\)).
