25 Calculer chacune des expressions suivantes. A= 5-4 B= 10 - (-5) C=-5-8 D=9 - 13 Er-8-(-7) F=6-(-7) Merciiii

Hello,

5 - 4 = 1

10 - (-5) = 10 + 5 = 15

- 5 - 8 = - 5 + (-8) = -13

9 - 13 = 9 + (-13) = -4

- 8 - (-7) = -8 + 7 = -1

6 - (-7) = 6 + 7 = 13

Réponse :

A = 1

B = 15

C = -13

D = -4

E = -1

F = 13
