A) 100-100:100x[100+100:10-(100-3)]=
100-1x(100+10-97)=
100-1x(110-97)=
100-1x13=100-13=87

B) 60+12x[214-240:(16-10)]-1000=
60+12x(214-240:6)-1000=
60+12x(214-40)-1000=
60+12x174-1000=
60+2088-1000=
2148-1000=1148
C) 1100-[(599-396+150)+37]:10=
1100-[(203+150)+37]:10=
1100-(353+37):10=
1100-390:10=
1100-39= 1061
D) (8991-111):10-[438-(400-40)]
8880:10-(438-360)
888-78= 810
