Bonjour
Calculer les expressions suivantes sans utiliser la calculatrice. ;)
1) A= (+3)+(+5)+(-6)
2) B= -3+(4-5+2)
3) C = (+6) + (−11) + (+2) + (−5)
4) D = (−2) + (+6) + (−14) + (+7)
5) E = (+12) + (−4) + (−8) + (+7) + (−11)
6) F = (−15) + (+5) + (−9) + (−2) + (+4)

bonjour

tu mettres profil collège et non lycée STP

A =  8 - 6 = 2

B  =   - 3 + 1 = -  2

C =  8 - 16 = - 8

D =  13 - 16 = - 3

E =  19 - 23 = - 4

F = 9 -  26 = -  17
