Răspuns:
a) 13-[-2+5-(-4+16)-2=13-[-2+5-(+12)-2]
=13-[3-(+12)-2]
=13-(-9-2)
=13-(-11)
=13+11
=24
b) 1-[(-4)-6×(-2)+(-3-5)÷2]+(-3)=1-[-4+12+(-8)÷2]+(-3)
=1-(8-4)-3
=1-4-3
=-3-3
=-6
c) [(-2)^3-10×(-5)^2+2×(-10+10÷2)]×(-10)=[-8-10×25+2×(-10+5)]×(-10)
=[-8-250+2×(-5)]×(-10)
=(-258-10)×(-10)
=-268×(-10)
=-2680
d) -32-(-2)^3+0^9+(-1)^10-(-4)^0
=-32-(-8)+0+1-(-1)
=-32+8+0+1+1
=-24+1+1
=-23+1
=-22
e) (-2)^101÷2^99-10×{-3-3×[(-3)^5÷3^4-2]}
=-20480÷9264-10×[-3-3×(-3-2)]
=-2,210708117-10×[-3-3×(-5)]
=-2,210708117-10×(-3+15)
=-2,210708117-10×12
=2,210708117-120
=-122,210708117
