Bonjour,
(-5)+(-3)= -5-3 = -8
b) (-4)-(+6) = -4-6 = -10
c) (+9)-(-3)= 9+3 = 12
d) (+4)+(+7)= 4+7 = 11
e) (+17)-(-5)+(+4)-(+5)-(-3)=
17+5+4-5+3 = 24
Bonjour !
a) (-5)+(-3) = -5 - 3 = -8
b) (-4)-(+6) = -4 - 6 = -10
c) (+9)-(-3) = 9 + 3 = 12
d) (+4)+(+7) = 4 + 7 = 11
e) (+17)-(-5)+(+4)-(+5)-(-3) = 17 + 5 + 4 - 5 + 3 = 24
J'espère t'avoir aidé. Bon courage !
