You asked:

Evaluate the expression: \(2 \cdot 5 \left(2 + 4 \cdot 1.5\right) + 4 - 3\)

MathBot Answer:

\[2 \cdot 5 \left(2 + 4 \cdot 1.5\right) + 4 - 3 = 81\]

\[\begin{aligned}2 \cdot 5 \left(2 + 4 \cdot 1.5\right) + 4 - 3& = 2 \cdot 5 \cdot \left(2 + 4 \cdot \left(1 + \frac{5}{10}\right)\right) + 4 - 3\\& = 2 \cdot 5 \cdot \left(2 + 4 \cdot \left(1 + \frac{1}{2}\right)\right) + 4 - 3\\& = 2 \cdot 5 \cdot \left(2 + 4 \cdot \frac{3}{2}\right) + 4 - 3\\& = 2 \cdot 5 \cdot \left(2 + 6\right) + 4 - 3\\& = 2 \cdot 5 \cdot 8 + 4 - 3\\& = 10 \cdot 8 + 4 - 3\\& = 80 + 4 - 3\\& = 84 - 3\\& = 81\end{aligned}\]
