You asked:

Evaluate the expression: \(3 \cdot {\left( -1 \right)}^{3} - 2 \cdot {\left( -1 \right)}^{2} + 4 \cdot -1 - 1\)

MathBot Answer:

\[3 \cdot {\left( -1 \right)}^{3} - 2 \cdot {\left( -1 \right)}^{2} + 4 \cdot -1 - 1 = -10\]

\[\begin{aligned}3 \cdot {\left( -1 \right)}^{3} - 2 \cdot {\left( -1 \right)}^{2} + 4 \cdot -1 - 1& = 3 \cdot \left(-1\right)^{3} - 2 \cdot \left(-1\right)^{2} + 4 \cdot -1 - 1\\& = 3 \cdot -1 - 2 \cdot \left(-1\right)^{2} + 4 \cdot -1 - 1\\& = -3 - 2 \cdot \left(-1\right)^{2} + 4 \cdot -1 - 1\\& = -3 - 2 \cdot 1 + 4 \cdot -1 - 1\\& = -3 - 2 + 4 \cdot -1 - 1\\& = -3 - 2 - 4 - 1\\& = -5 - 4 - 1\\& = -9 - 1\\& = -10\end{aligned}\]
