Sagot :
A=5+3 x (-2)
= 5 - 6
= -1
B=-6+ (-4 ) x 5
= - 6 - 20
= - 26
C= -5 x 3 +7
= -15 + 7
= 8
D=(-1-7) x (-6 )
= -8 x -6
= 48
E= -4 x ( -7 + 13 )
= -4 x 6
= -24
En espérant t'avoir aidé.
A=5+3 x ( -2 )
= 5 - 6
= -1
B=-6+ ( -4 ) x 5
= - 6 - 20
= - 26
C= -5 x 3 +7
= -15 + 7
= 8
D=( -1 -7 ) x ( -6 )
= -8 x -6
= 48
E= -4 x ( -7 + 13 )
= -4 x 6
= -24
