Question

(72:6+128) :2x9=?
900-(320:8+480:6)=?
700+(330-420:7-136)=?
600+(399:1-144x0)=?
300:100+(255-160:160)=?
(235+325) :7x4-127=?

Answer 1

(72:6+128) : 2*9 = (12+128) :2*9 = 140 :2 *9 = 70 * 9 = 630
900 - (320 :8+480:6)=900 - (40+80) = 900 - 120 = 780
700 + (330-420:7-136) =700 + (330-60-136) = 700 + (270-136)=700+134=834
600+(399:1-144*0)=600+(399-0)=600+399=999
300:100+(255-160:160)=300:100+(255-1)=300:100+256=3+256=259
(235+325):7*4-127=560:7*4-127=80*4-127=320-127=193
