Réponse :
A = ( -12) / (-3) +30 / (-6)
les priorités de calculs : on fait les divisions et multiplications en premier
= 4 +(-5)
= -1
B = 19+14 / (-7) + (-30) / (-5 )
= 19 + (-2) + 6
= 23
C= -1 - (-5) x (-3) + 42/ (-7)
= -1 - 15 + (-6)
= -16 + (-6)
= -22
D = ( -2 x( -2) x(-10) ) / ( -1-4 )
= ( 4x-10 ) / ( -5 )
= -40 / -5
= 8
