# How do you simplify -3*12 - *18 + *72 + 8*75?

Treating the $\cdot$ symbol as multiplication, the given expression makes no sense
If $- 3 \cdot 12 \textcolor{red}{- \cdot} 18. . .$ is meant to be interpreted as
$\textcolor{w h i t e}{\text{XXX}} - 3 \times 12 \textcolor{red}{- \times} 18. . .$
then either the $\textcolor{red}{-}$ or the $\textcolor{red}{\cdot}$ should be omitted
