Svp aider moi je suis en 4e 131 Calculer. A=-5 – 3 x (5 -(5 – 13)) B=(7 - 12): (12 – (1 +8 x 2)). C=-20+ ((-3)*(-7 – 3) – 16)

bonjour

A = - 5 - 3 x ( 5 - ( - 8 )  

A  = - 5 - 3 x ( 5 + 8 )

A = - 5 - 3 x 13

A = - 5 - 39 = - 44

b = - 5 :  ( 12 -  17 )  

b = -  5 : - 5

b =  - 5/- 5 = 1

C =  -20 + (( -3 * ( - 10 ) - 16 ))

C = - 20 + (  30  - 16 )

C = - 20 + 14 = - 6

Bonjour,

A=-5 – 3 x (5 -(5 – 13))

= -5 -3( 5 +8)

= -5 -3* 13

= -5 -39

= - 44

B=(7 - 12): (12 – (1 +8 x 2)).

= -5/ ( 12 -1-16)

= -5/  5

=-1

C=-20+ ((-3)*(-7 – 3) – 16)

= -20 +( -3* -10 -16)

= -20 + 30 -16

= -6
