Answer 1

600:10:2+125:5-270:9=
600:10:2=60:2=30
125:5=25
270:9=30
30+25-30=25
deci->600:10:2+125:5-270:9=25


300-123*4:6:1+88*4=
123*4:6:1=492:6:1
=82:1=82
88*4=352
300-82+352=218+352
=570

deci:300-123*4:6:1+88*4=570


1200+456*12-780:20*40:1

456*12=5472
780:20*40:1=39*40:1
=1560:1=1569
1200+5471-1569=6671-1569
=5102
deci 1200+456*12-780:20*40:1=5102
