Evaluate the expression: \(7 \cdot 20 - 9 \cdot 1 + 6 - 5 + 9 \cdot 2 - 17\)

MathBot Answer:

\[7 \cdot 20 - 9 \cdot 1 + 6 - 5 + 9 \cdot 2 - 17 = 133\]


\[\begin{aligned}7 \cdot 20 - 9 \cdot 1 + 6 - 5 + 9 \cdot 2 - 17& = 140 - 9 \cdot 1 + 6 - 5 + 9 \cdot 2 - 17\\& = 140 - 9 + 6 - 5 + 9 \cdot 2 - 17\\& = 140 - 9 + 6 - 5 + 18 - 17\\& = 131 + 6 - 5 + 18 - 17\\& = 137 - 5 + 18 - 17\\& = 132 + 18 - 17\\& = 150 - 17\\& = 133\end{aligned}\]
