| $$ \begin{aligned}-6(-10n-3)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-(-60n-18) \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}60n+18\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{6} $ by $ \left( -10n-3\right) $ $$ \color{blue}{6} \cdot \left( -10n-3\right) = -60n-18 $$ |
| ② | Remove the parentheses by changing the sign of each term within them. $$ - \left(-60n-18 \right) = 60n+18 $$ |
