10(2)(2)+(20-1)(2)=
You asked:
Evaluate the expression: \(10 \cdot 2 \cdot 2 + \left(20 - 1\right) \cdot 2\)
MathBot Answer:
\[10 \cdot 2 \cdot 2 + \left(20 - 1\right) \cdot 2 = 78\]
\[\begin{aligned}10 \cdot 2 \cdot 2 + \left(20 - 1\right) \cdot 2& = 20 \cdot 2 + \left(20 - 1\right) \cdot 2\\& = 40 + \left(20 - 1\right) \cdot 2\\& = 40 + 19 \cdot 2\\& = 40 + 38\\& = 78\end{aligned}\]
