You asked:

Evaluate the expression: \(30 - \left(4 + 12 - 4 - 3 \cdot \left(10 - 3\right)\right)\)

MathBot Answer:

\[30 - \left(4 + 12 - 4 - 3 \cdot \left(10 - 3\right)\right) = 39\]

\[\begin{aligned}30 - \left(4 + 12 - 4 - 3 \cdot \left(10 - 3\right)\right)& = 30 - \left(4 + 12 - 4 - 3 \cdot 7\right)\\& = 30 - \left(4 + 12 - 4 - 21\right)\\& = 30 - \left(16 - 4 - 21\right)\\& = 30 - \left(12 - 21\right)\\& = 30 - -9\\& = 30 + 9\\& = 39\end{aligned}\]
