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
