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
