| ① | Add $ \dfrac{-35}{6} $ and $ \dfrac{35}{6} $ to get $ \dfrac{0}{6} $. To add expressions with the same denominators, we add the numerators and write the result over the common denominator. $$ \begin{aligned} \frac{-35}{6} + \frac{35}{6} & = \frac{-35}{\color{blue}{6}} + \frac{35}{\color{blue}{6}} =\frac{ -35 + 35 }{ \color{blue}{ 6 }} = \\[1ex] &= \frac{0}{6} \end{aligned} $$ |
