Bonsoir pouvait cous m aider a cette ex pour delain svp merci d avance

Exercice 4: Transformer les soustractions en additions puis calculer : E = (-5)-7-(-3) + 11 F = 4+ (-3) -(-6) +2 G=(-2) + 1 - 4+ (-3) H = 11-(-3) + (− 4 ) − 2 + 11 ​


Sagot :

E = (-5)-7-(-3) + 11

  = -5-7+3+11

  = -12+3+11

  = 2

F = 4+ (-3) -(-6) +2

  = 4+(-3) +6 +2

  = 1+6+2

  = 9

G = (-2) + 1 - 4+ (-3)

  = -2+1-4-3

  = -1-4-3

  = -8

H = 11-(-3) + (− 4 ) − 2 + 11 ​

  = 11+3-4-2+11

  = 14-4-2+11

  = 10-2+11

  = 8+11

  = 19
