Question
bonjour aider moi svp
calculer chaque experionsse:
A=42-(8+5×6)-1
B=12+(196-7)×4+(3×8+6)
C=50÷5×(11-4)-4×(5×2-6)
D=(24-8÷2)÷(17-12)*
calculer chaque experionsse:
A=42-(8+5×6)-1
B=12+(196-7)×4+(3×8+6)
C=50÷5×(11-4)-4×(5×2-6)
D=(24-8÷2)÷(17-12)*

1. Réponse Jufoxou
A = 42-(8+5x6)-1
A = 42-(8+30)-1
A = 42-38-1
A = 3
B = 12+(196-7)x4+(3x8+6)
B = 12+189x4+30
B = 12+756+30
B = 798
C = 50÷5x(11-4)-4x(5x2-6)
C = 50÷5x7-4x4
C = 70-16
C = 54
D = (24-8÷2)÷(17-12)
D = 20÷5
D = 4
