Bonjour,
Calculer:
F=(-2-5)*4-9 = 4(-7)-9= -28-9= -37
G=(-2)+(-3)*5 = -2-15= -17
H=-7-5*4 = 7-20= ....calcule
I=7*(-6)-(-2) = -42+2= - ... calcule
J=3*5-(5-12)= 15-(-7)= 15+7= ...calcule
K=5-(25-5*6) = 5-(25-30)= 5-(-5)= 5+5= ...calcule
L=6*(-7)-15*(-3) = -42+45= ...calcule
M= -38+8*7+16 / (-4) = -38+56-4= -... calcule
N=(2-6*(-3)) / (-5*11+35) = (2+18)/(-55+35)= 20/ -20= - ...calcule
O=7-(-3+(5-4*3))= 7-(-3+(5-12))= 7-(-3+(-7))=7-(-3-7)=7-(-10)=7+10= ...calcule
