bonsoir
G = - 5 - 12 = - 17
H = 9 - 13 = - 4
I = 7.4 - 0.4 = 7
J = 13 - 13 = 0
K = 4 + 10 = 14
L = 2.5 - 6 = - 3.5
M = 11.5 - 1.5 = 10
N = 6 + 14 = 20
P = 7 - 20 = - 13
Q = 5 - 7 + 14 + 9 + 3 = 31 - 7 = 24
R = 14 - 14 + 3 - 14 + 3 + 4 .8 + 3.2 - 2.7 = 14 - 16.7 = - 2. 7
S = 2.5 + 4.8 + 3.2 - 2.7 = 10.5 - 2.7 = 7 .8
T = - 7 + 8.4 + 4 + 7 - 4 = 19.4 - 11 = 8.4
