Answer

$\sf2) \: \: \: (3) - ( + 8) = - 3 - 8 = - 11$

$\sf4) \: \: \: ( + 3) - ( + 3) = 3 - 3 = 0$

$\sf6) \: \: \: ( + 6) - ( + 2) = 6- 2 = 4$

$\sf8) \: \: \: ( + 9) - ( + 4) = 9 - 4 = 5$

$\sf10) \: \: \: ( + 4) - (0) = 4 - 0= 4$

$\sf12) \: \: \: ( - 3) - ( + 1) = - 3 - 1 = - 4$

$\sf14) \: \: \: ( + 3) - ( + 5) = 3 - 5 = - 2$

$\sf16) \: \: \: ( + 9) - ( - 5) = 9 + 5 = 14$

$\sf18) \: \: \: ( + 7) - ( + 3) = 7 - 3 = 4$

$\sf20) \: \: \: ( + 2) - ( + 5) = 2 - 5 = - 3$
