You asked:

Evaluate the expression: \(12 - 15 + 18 - 19 - \left(-14 + 15 - 8 + 3\right)\)

MathBot Answer:

\[12 - 15 + 18 - 19 - \left(-14 + 15 - 8 + 3\right) = 0\]

\[\begin{aligned}12 - 15 + 18 - 19 - \left(-14 + 15 - 8 + 3\right)& = 12 - 15 + 18 - 19 - \left(1 - 8 + 3\right)\\& = 12 - 15 + 18 - 19 - \left(-7 + 3\right)\\& = 12 - 15 + 18 - 19 - -4\\& = 12 - 15 + 18 - 19 + 4\\& = -3 + 18 - 19 + 4\\& = 15 - 19 + 4\\& = -4 + 4\\& = 0\end{aligned}\]
