a)-30+[-10-(-8-4)-1+3]
= -30 + [-10-(-12)-1+3]
= -30+[-10+12-1+3]
= -30 + 4
= -26


b)-80÷(-20)×(-3)-30
= 80 × (-3) - 30
= -240 -30
= -270


c)70×(-2)×(-10)×8
= -140 × (-80)
= 11200


D)-(-8-4)+(-10×8)-10
= 8 + 4 + (-80) -10
= 12 - 80 - 10
= -68 - 10
= -78


E)-1-{-8+[-30+(-8-4)+1]-2}
= -1-{-8+[-30+(-12)+1]-2}
= -1-{-8+ [-30-12+1]-2}
=-1-(-8+(-41)-2)
= -1-(-8-41-2)
-1-(-51)
= -1+51
= 50


F)-30 +(-8-40)-35
-30+ (-48) -35
= -30 - 48 - 35
= -113


G)60×(-30)×(-6÷(-2)
= -2 × 3
= -6
H)-8+(-4-5)×(-3)+10
= -8 + (-9) × (-3) + 10
= -8 + 27 + 10
= 29

i)-900÷(-30) ÷(-15)
= 30 ÷ (-15)
= -2
j)-10-(-8-10)÷(-2)+5×(-10)
= -10 - (-18) ÷ (-2) + (-50)
= -10 - 9 - 50
= - 69
