Bonjour,

Calculer:

A= (-5+1)+(6-11)-(-3-17)= -4-5-(-20)= -9+20= 11

B=(-3+1-9)-(6-11+3)+(-5-11-10)= -11-(-2)-26)= -11+2-26= -9-26= -35

C= (-12+1-12)-[(-4-11)-(-1-1)]= -23-[ (-15)-(-2) ]= -23-(-15+2)= -23-(-13)= -23+13= -10

D = -5+5,6-6-8-14+5= -5+5-6-8-14+5.6== 0 - 14-14+5.6= -28+5.6=  - 22.4

E = 23-(-6) +9-12-6-(-14)= 23+6+9-12-6+14= 34
