Answer 2

$\frac{1}{3} - \frac{1}{2} + \frac{1}{6} \\ \\ \frac{1 \times 2}{3 \times 2} - \frac{1}{2} + \frac{1}{6} \\ \\ \frac{1 \times 2}{3 \times 2} - \frac{1 \times 3}{2 \times 3} + \frac{1}{6} \\ \\ \frac{2}{3 \times 2} - \frac{1 \times 3}{2 \times 3} - \frac{1}{6} \\ \\ \frac{2}{6} - \frac{1 \times 3}{2 \times 3} + \frac{1}{6} \\ \\ \frac{2}{6} - \frac{3}{2 \times 3} + \frac{1}{6} \\ \\ \frac{2}{6} - \frac{3}{6} + \frac{1}{6} \\ \\ \frac{2 - 3 + 1}{6} \\ \\ 2 - 3 + 1 \\ \\ 3 - 3 \\ 0 \\ \\ \frac{0}{6} \\ \\ = 0 \\ \\ \Large\mathscr{\red{Attard}}$
