bonjour
A = 9 - 16 - 8 + 22 = 31 - 24 = 7
B = - 48 + 34 + 26 - 12 = 60 - 60 = 0
C = - 7.5 + 12.3 - 2.5 - 5 + 12.7 = 25 - 15 = 10
D = - 35 + 8 + 14 - 26 = 22 - 61 = - 39
E = 54 - 17 + 11.5 - 6 + 4 = 69.5 - 23 = 46.5
F = - 18 - 17 + 16 + 15 + 14 = 45 - 35 = 10
I = 15 - 22 - 18 = 15 - 40 = - 25
J = - 21 + 6 - 14 = 6 - 35 = - 29
K = 38 - 54 - 4 + 20 = 58 - 58 = 0
