ori=inmultire

Answer 1

a)
-5+(-4+6)(-2)-(-8)×0+(-11+6+8)×(-100)=
=-5+2×(-2)+8×0+(-11+14)×(-100)=
=-5-4+0+3×(-100)=
=-9-3×100=
=-9-300=
=-309
b)
-10×{100-[100-(100-1)]}=
=-10×[100-(100-99)]=
=-10×(100-1)=
=-10×99=
=-990

c)
-5[-4+(-6+2-0)×(-3)-(11-7)×2]-(-4)×(-1)=
=-5[-4+(-4)×(-3)-4×2]-4=
=-5(-4+12-8)-4=
=-5(-12+12)-4=
=-5×0-4=
=0-4=
=-4
