Ayudenme porfa porfa porfa

Answer 1

16:[-40+34-(-10)](42:-7)
=16:[-40+34+10](-6)
=16:[4](-6)
=16:-24
=-2/3
=-0.66

2{3[-2-(-8)]}:3(-5+-1)
=2{3[-2+8]}:3(-5-1)
=2{3[6]}:3(-6)
=36:-18
=-2

(-2x11+-3)-(-8:-2)
=(-22-3)-(4)
=-25-4
=-29

-7{-2[-2-(-8)]}:3(-5+-1)
=-7{-2[-2+8]}:3(-6)
=-7{-2[6]}:-18
=84:-18
=14/3
=4.666
