4(3-5)2 - 7(1-2)2
You asked:
Evaluate the expression: \(4 \cdot \left(3 - 5\right) \cdot 2 - 7 \cdot \left(1 - 2\right) \cdot 2\)
MathBot Answer:
\[4 \cdot \left(3 - 5\right) \cdot 2 - 7 \cdot \left(1 - 2\right) \cdot 2 = -2\]
\[\begin{aligned}4 \cdot \left(3 - 5\right) \cdot 2 - 7 \cdot \left(1 - 2\right) \cdot 2& = 4 \cdot -2 \cdot 2 - 7 \cdot \left(1 - 2\right) \cdot 2\\& = -8 \cdot 2 - 7 \cdot \left(1 - 2\right) \cdot 2\\& = -16 - 7 \cdot \left(1 - 2\right) \cdot 2\\& = -16 - 7 \cdot -1 \cdot 2\\& = -16 - -7 \cdot 2\\& = -16 - -14\\& = -16 + 14\\& = -2\end{aligned}\]
