82+9*(5*5-5):(5+5*5-4*5):(9-81:9+90:10)
=82+9*(25-5):(5+25-20):(9-9+10)
=82+9*20:30-20:1+10
=82+180:30-20:1
=82+6-20+10
=78

15-3*6:(3*3*3:3+0:5)+30:(3:3+5)
=15-18:(27:3+0)+30:(1+5)
=15-18:(9+0)+30:6
=15-18:9+5
=15-2+5
=13+5
18



82+9x(5x5-5):(5+5x5-4x5):(9-81:9+90:10)=
82+9x20:10:9=
82+ 180:10:9=
82+2=84

15-3x6:(3x3x3:3+0:5)+30:(3:3+5)=
15-3x6:9+30:6=
15-2+5=18
