Question

[(0:90+90:2) x (329:7+159:3)]:(1000:100 x 10)=
6+5 x [30+5 x (3+5 x 6)x3-25]-3=
200+240:2-[340:10+2 x (10+6+9)]=
??????????????????????

Answer 1

[(0:90+90:2)x(329:7+159:3)]:(1000:100x10)=
[(0+45)x(47+53)]:(10x10)=
(45x100):100=
4500:100=45

6+5x[30+5x(3+5x6)x3-25]-3=
6+5x[30+5x(3+30)x3-25]-3=
6+5x(30+5x33x3-25)-3=
6+5x(30+165x3-25)-3=
6+5x(30+495-25)-3=
6+5x(525-25)-3=
6+5x500-3=
6+2500-3=
2506-3=2503

200+240:2-[340:10+2x(10+6+9)]=
200+120-(34+2x25)=
200+120-(34+50)=
200+120-75=
320-75=245
