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)*

  • 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
