8.  [(2780+1428)+182x4]-72:8=4927 
9. [(5014-2020)+34x18]-(980+890)=1646
10. [(100:10)+50x20]-(7000-6815)=825
11. 68x3 -  25x2=79
8)[(2780+1428)+(182×4)]-(72÷8)=4208+728-9=3471

9)[(5014-2020)+(34×18)]-(980+890)=2994+612-1870=1730

10)(100÷10)+(50×20)-(7000-6815)=10+1000-185=825

11)( 68×68×68)-(25×25)=314382
