Question

[(8+8:8):9+(9+9:9):10-1]-1=
(91-89)x(201+6x32)-3x183:9=
[23x235+(100x4500-36990)]:5=
126x0+25x[125:5x(54x61-88x37)]=
[(125x7-190):5-29]:3x9+599=

Answer 1

[(8+1):9+(9+1):10-1]-1=(9:9+10:10-1)-1=(1+1-1)-1=1-1=0
2x(201+192)-549:9=2x393-61=786-61=725
[5405+(450000-36990)]:5=(5405+413010):5=418415:5=83683
0+25x[25x(3294-3256)]=25x(25x38)=25x950=23750
[(875-190):5-29]:3x9+599=(685:5-29):3x9+599=(137-29):3x9+599=108:3x9+599=
36x9+599=324+599=923
