calculer en détaillant les étapes : D = [(86+2)/5-12]x22-22
A = 7+16x6
C = 15x(9+2x26)+9x(15+11)
B = 62+14-14x5+5
A = 7+16x6= = 7 + 96= 103
C = 15x(9+2x26)+9x(15+11)
= 15x(9+52) +9x26
= 15x61 + 9x26
= 915 + 234= 1149
B = 62+14-14x5+5
= 62+14-70+5
= 81 - 70= 11
D = [(86+2)÷5-12]x22-22
= [88÷5-12]x22-22
= [17.6-12]x22-22
= 5.6x22-22
= 123.2 - 22= 101.2
Voilà;) Niinii:)
