You asked:

Evaluate the expression: \(18 - \frac{10 \cdot \left(4 + 12 - 7\right)}{18}\)

MathBot Answer:

\[18 - \frac{10 \cdot \left(4 + 12 - 7\right)}{18} = 13\]

\[\begin{aligned}18 - \frac{10 \cdot \left(4 + 12 - 7\right)}{18}& = 18 - 10 \cdot \left(4 + 12 - 7\right) \cdot \frac{1}{18}\\& = 18 - 10 \cdot \left(16 - 7\right) \cdot \frac{1}{18}\\& = 18 - 10 \cdot \frac{9}{18}\\& = 18 - \frac{10}{2}\\& = 18 - 5\\& = 13\end{aligned}\]
