You asked:

Evaluate the expression: \(18 + 4 - 3 \left(3 + 2 \left(3 - 2\right) \cdot 7\right)\)

MathBot Answer:

\[18 + 4 - 3 \left(3 + 2 \left(3 - 2\right) \cdot 7\right) = -29\]

\[\begin{aligned}18 + 4 - 3 \left(3 + 2 \left(3 - 2\right) \cdot 7\right)& = 18 + 4 - 3 \cdot \left(3 + 2 \cdot \left(3 - 2\right) \cdot 7\right)\\& = 18 + 4 - 3 \cdot \left(3 + 2 \cdot 1 \cdot 7\right)\\& = 18 + 4 - 3 \cdot \left(3 + 2 \cdot 7\right)\\& = 18 + 4 - 3 \cdot \left(3 + 14\right)\\& = 18 + 4 - 3 \cdot 17\\& = 18 + 4 - 51\\& = 22 - 51\\& = -29\end{aligned}\]
