$( + 6) - ( - 8) = 6 + 8 = 14 \\ ( - 1) - ( - 3) = - 1 + 3 = 2 \\ ( - 9) - ( + 10) = - 9 - 10 = - 19$

$( + 9) - ( - 5) = 9 + 5 = 14\\ ( + 4) - ( + 4) = 4 - 4 = 0 \\ ( - 6) - ( - 11) = - 6 + 11 = 5$

$( - 7.1) - ( - 7.1) = - 7.1 + 7.1 = 0 \\ ( - 7.1) - ( + 7.1) = - 7.1 - 7.1 = - 14.2 \\ ( + 7.1) - ( - 7.1) = 7.1 + 7.1 =14.2$

$- 5.7 - ( - 1.3) = - 5.7 + 1.3 = - 4.4 \\ - 7.5 - ( - 2.1) = - 7.5 + 2.1 = - 5.4 \\ - 8.9 - ( - 3.7) = - 8.9 + 3.7 = - 5.2$

$- 6 - ( + 8.1) = - 6 - 8.1 = - 14.1 \\ - 5 - ( + 6.7) = - 5 - 6.7 = - 11.7 \\ - 8 - ( + 9.5) = - 8 - 9.5 = - 17.5$

$3.5 - ( + 7) = 3.5 - 7 = - 3.5 \\ 3.6 - ( - 5) = 3.6 + 5 = 8.6 \\ 4.6 - ( + 2.5) = 4.6 - 2.5 = 2.1$

$\frac{1}{2} - ( + 4) = 0.5 - 4 = - 3.5 \\ - \frac{5}{11} - ( - \frac{5}{11} ) = - \frac{5}{11} + \frac{5}{11} = 0 \\ - 5 - ( - 2 \frac{1}{3} ) = - 4 \frac{3}{3} + 2 \frac{1}{3} = - 2 \frac{2}{3} \\ - 8 - ( - \frac{1}{7} ) = - 8 + \frac{1}{7} = - 7 \frac{6}{7} \\ \frac{1}{6} - ( + 3) = \frac{1}{6} - 2 \frac{6}{6} = - 2 \frac{5}{6} \\ - \frac{5}{12} - ( - 4) = - \frac{5}{12} + 4 = 3 \frac{12}{12} - \frac{5}{12} = 3 \frac{7}{12}$
