You asked:

Evaluate the expression: \(6 \left(7 - 2 \cdot 8 - 10\right) + 10 \left(10 + 20 + 80 - 100\right)\)

MathBot Answer:

\[6 \left(7 - 2 \cdot 8 - 10\right) + 10 \left(10 + 20 + 80 - 100\right) = -14\]

\[\begin{aligned}6 \left(7 - 2 \cdot 8 - 10\right) + 10 \left(10 + 20 + 80 - 100\right)& = 6 \cdot \left(7 - 2 \cdot 8 - 10\right) + 10 \cdot \left(10 + 20 + 80 - 100\right)\\& = 6 \cdot \left(7 - 16 - 10\right) + 10 \cdot \left(10 + 20 + 80 - 100\right)\\& = 6 \cdot \left(-9 - 10\right) + 10 \cdot \left(10 + 20 + 80 - 100\right)\\& = 6 \cdot -19 + 10 \cdot \left(10 + 20 + 80 - 100\right)\\& = -114 + 10 \cdot \left(10 + 20 + 80 - 100\right)\\& = -114 + 10 \cdot \left(30 + 80 - 100\right)\\& = -114 + 10 \cdot \left(110 - 100\right)\\& = -114 + 10 \cdot 10\\& = -114 + 100\\& = -14\end{aligned}\]
