Step-by-step explanation:
12-4(-8+15)
= 12-4(7)
= 8(7)
= 56
-15+11
= -4
(-3)(86)-2(72)
=(-258)-2(72)
=(-258)(144)
=37,152
15-(-8)(-12+3)
=15-(-8)(-9)
=23(9)
=207
(-8)(-14+10)-64
=(-8)(-4)-64
=32-64
= -32
(-14)(-9+5)
=(-14)(-4)
= 56
(-5)(-12+8)(-7)-16
=(-5)(-4)(-7)-16
=9(-7)-16
= -63-16
= -79
(-2)[-15+12(-3)-5(-5)]
=(-2)[-15+(-36)-5(-5)]
=(-2)[-15+(-36)(25)]
=(-2)[-15+(-36)(25)]
=(-2)[-15+(-900)]
=(-2) -915
= 1830
