Bonjour
a= -6+9= 3
b=(4-3)+(-9+2)= 1 - 7 = - 6
c=(-8+2)-3+(4-5)= - 6 - 3 - 1 = - 10
d=(-25+6)-4+(2-2)= - 19 - 4 = - 23
e=(28-4)-(6-2)= 24 - 4 = 20
f=(54-9)+(4-3)= 45 + 1 = 46
g=(108-54)+(29-3)= 54 + 26 = 80
h=(36-2)+(3-2)= 34 + 1 = 35
i=(7-9)+(16-4)= - 2 + 12 = 10
j=79-(4-6)+9= 79 - (- 2) + 9 = 79 + 9 + 2 = 90
k=(64-30)+(90-9+3)= 34 + 84 = 118.
