To find the sum or difference for the expression provided, let's break it down step-by-step. For the first part, \(-5 + 12\): \(-5 + 12 = 7\). Next, for \(9 - 19\): \(9 - 19 = -10\). Now, let's evaluate \(-4 + (-6)\): \(-4 + (-6) = -10\). Now, we need to sum all those results together: \(7 + (-10) + (-10) = 7 - 20 = -13\). The last part is \(4 - (-9)\): \(4 - (-9) = 4 + 9 = 13\). Now, putting it all together: The final result of combining the parts is \(-13 + 13 = 0\). So, the complete expression evaluates to **0**!
