8 (7-1-2-5) -4 +3 -2 (6-5-7)
You asked:
Evaluate the expression: \(8 \cdot \left(7 - 1 - 2 - 5\right) - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right)\)
MathBot Answer:
\[8 \cdot \left(7 - 1 - 2 - 5\right) - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right) = 3\]
\[\begin{aligned}8 \cdot \left(7 - 1 - 2 - 5\right) - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right)& = 8 \cdot \left(6 - 2 - 5\right) - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right)\\& = 8 \cdot \left(4 - 5\right) - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right)\\& = 8 \cdot -1 - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right)\\& = -8 - 4 + 3 - 2 \cdot \left(6 - 5 - 7\right)\\& = -8 - 4 + 3 - 2 \cdot \left(1 - 7\right)\\& = -8 - 4 + 3 - 2 \cdot -6\\& = -8 - 4 + 3 - -12\\& = -8 - 4 + 3 + 12\\& = -12 + 3 + 12\\& = -9 + 12\\& = 3\end{aligned}\]
