a) 15+15:15x(15+15x15)=15+15:15×240=

15+1×240=15+240=255

b) 250+60:(50-2x15)x50=250+60:20×50=

250+3×50=250+150=400

c)110:10x(110-20x4)+670=110:10×30+670=

11×30+670=330+670=1000

d) (444:4+400-400:10):3=(111+409-40):3=

(520-40):3=480:3=160

e) 100-100:100x[100+100:10-(100-75:25)]=

100-100:100×(100+100:10-97)=

100-100:100×13=100-1×13=100-13=87

f) 50+12x[214-240:(16-2x5)]-10x100=

50+12×(214-240:6)-10×100=

50+12×(214-20)-10×100=

50+12×194-10×100=

50+2328-1000=50+1328=1378

g) 110x10-[(599-99x4+30x5)+370:10]:10=

1100-(599-396+150+37):10=

1100-(203+187):10=1100-390:10=1100-39=1061

h) (9x999-999:9):10-[444-6-(400-400:10)]=
