Answer 1

a)
15+15:15x(15+15x15)=15+1x(15+225)=15+240=255
b)
250+60:(50-2x15)x50=250+60:(50-30)x50=250+60:20x50=250+30x50=
250+1500=1750
c)
110:10x(110-20x4)+670=11x(110-80)+670=11x30+670=330+670=1000
d)
(444:4+400-400:10):3=(111+400-40):3=471:3=157
e)
100-100:100x[100+100:10-(100-75:25)]=100-1x[100+10-(100-3)]=
100-(100+10-97)=
100-13=87
f)
50+12x[214-240:(16-2x5)]-10x100=50+12x[214-240:(16-10)]-1000=
50+12x(214-240:6)-1000=50+12x(214-40)-1000=
50+12x174-1000=50+2088-1000=2138-1000=1138

g)
110x10-[(599-99x4+30x5)+370:10]:10=1100-[(599-396+150)+37]:10=
1100-(353+37):10=1100-390:10=1100-39=1061
h)
(9x999-999:9):10-[444-6-(400-400:10)]=(8991-111):10-[444-6-(400-40)]=
8880:10-(444-6-360)=888-78=810
