(-0.1)÷1/2×(-100)
=(-0.1)×(-100)×2
=10×2
=20
[-3/4×(-2/3-1/3)]×0
=[-3/4×(-1)]×0
=3/4
(-2)^3+(-2)^2-2^3-2^2
=2^3+2^2-2^3-2^2
=(2^3-2^3)+(2^2-2^2)
=0
23÷[(-2)^3-(-4)]
=23÷(-8+4)
=23÷(-4)
=-5又3/4
-(-2)^3+[2+(-3)^4]×[(-5)×(-6)-7-8+9]
=8+(2+81)×(30-6)
=8+83×24
=8+1992
=2000
(-1)÷(-19/93)÷(-9393/1919)
=(-1)÷[(-19/93)×(-9393/1919)]
=(-1)÷1
=-1
