MathBot Answer:

\[-25 + 12 - 8 + -15 \cdot .1 \cdot .2 = - \frac{213}{10} = -21.3\]

\[\begin{aligned}-25 + 12 - 8 + -15 \cdot .1 \cdot .2& = -25 + 12 - 8 - \frac{15}{10} \cdot \frac{2}{10}\\& = -25 + 12 - 8 - \frac{3}{2} \cdot \frac{2}{10}\\& = -25 + 12 - 8 - \frac{3}{10}\\& = -13 - 8 - \frac{3}{10}\\& = -21 - \frac{3}{10}\\& = - \frac{213}{10}\end{aligned}\]
