bonjour

A = ( +9 ) + ( -8 ) = 9 - 8 = 1

B = ( +12 ) + ( -7 ) = 12 - 7 = 5

C = ( -14 ) - ( +13 ) = -14 - 13 = - 27

D = ( -6 ) - ( +3 ) = - 6 - 3 = - 9

E = ( +7 ) + ( +14 ) = 7 + 14 = 21

F = ( -13 ) + ( -12 ) = -13 - 12 = - 25

G = ( +4 ) - ( +8 ) = 4 - 8 = -4

H = ( -8 ) + ( -8 ) = -8 - 8 = -16

A = (+9) + (-8) = 9 - 8 = 1

B = (+12) + (-7) = 12 - 7 = 5

C = (-14) - (+13) = -14 - 13 = -27

D = (-6) - (+3) = -6 - 3 = -9

E = (+7) + (+14) = 7 + 14 = 21

F = (-13) + (-12) = -13 - 12 = -25

G = (+ 4) -  (+8) = 4 - 8 = -4

H = (-8) + (-8) = -8 - 8 = -16
