You asked:

Evaluate the expression: \(-\left( -20 + 21 - 32 + 18 \right) + -15 + 3 - 2 - 9\)

MathBot Answer:

\[-\left( -20 + 21 - 32 + 18 \right) + -15 + 3 - 2 - 9 = -10\]

\[\begin{aligned}-\left( -20 + 21 - 32 + 18 \right) + -15 + 3 - 2 - 9& = - \left(-20 + 21 - 32 + 18\right) - 15 + 3 - 2 - 9\\& = - \left(1 - 32 + 18\right) - 15 + 3 - 2 - 9\\& = - \left(-31 + 18\right) - 15 + 3 - 2 - 9\\& = - -13 - 15 + 3 - 2 - 9\\& = 13 - 15 + 3 - 2 - 9\\& = -2 + 3 - 2 - 9\\& = 1 - 2 - 9\\& = -1 - 9\\& = -10\end{aligned}\]
