$- \frac{1}{3} + \frac{1}{2} = - \frac{2}{6} + \frac{3}{6} = \frac{1}{6}$
$- \frac{4}{7} - \frac{3}{14} = - \frac{8}{14} - \frac{3}{14} = - \frac{11}{14}$
$- 2 \frac{5}{6} - 3 \frac{1}{3} = - 2 \frac{5}{6} - 3 \frac{2}{6} = - 5 \frac{7}{6} = \\ = - 6 \frac{1}{6}$
$7 \frac{1}{5} - 4 \frac{4}{15} = 7 \frac{3}{15} - 4 \frac{4}{15 } = \\ = 6 \frac{18}{15} - 4 \frac{4}{15} = 2 \frac{14}{15}$
$2 \frac{1}{6} - \frac{3}{8} = 2 \frac{4}{24} - \frac{9}{24} = 1 \frac{28}{24} - \frac{9}{24} = \\ = 1 \frac{19}{24}$
$- \frac{1}{12} + \frac{7}{60} = - \frac{5}{60} + \frac{7}{60} = \frac{2}{60} = \frac{1}{30}$
$- \frac{10}{9} + 1 \frac{8}{9} = - 1 \frac{1}{9} + 1 \frac{8}{9} = \frac{7}{9}$
$- 3 \frac{1}{2} + 7 \frac{1}{3} = - 3 \frac{3}{6} + 7 \frac{2}{6} = \\ = - 3 \frac{3}{6} + 6 \frac{8}{6} = 3 \frac{5}{6}$
