bonjour, c'etait pour mon dm de maths:
A= (+5)+(-7)x(-3)
B= (+5)x((-7)+(-2))x(+3)
C= (+5)x(-7)+(+3)x(-2)
D= (-7)-(+3)x((+5)+(-2))
A= (+5)+(-7)x(-3)
B= (+5)x((-7)+(-2))x(+3)
C= (+5)x(-7)+(+3)x(-2)
D= (-7)-(+3)x((+5)+(-2))

A= (+5)+(-7)x(-3)
= (+5)+(21)
=26
B=(+5)x((-7)+(-2))x(+3)
=(+5)x(-9)x(+3)
=(-45)x(+3)
= -135
C=(+5)x(-7)+(+3)x(-2)
=(-35)+(+3)x(-2)
=(-35)+(-6)
= -41
D=(-7)-(+3)x((+5)+(-2))
=(-7)-(+3)x(+3)
=(-7)-(+9)
= -16
