(270+57x10):14-85:17=
85-(36+2x17):14=
1305:29-21x(36:6-5)

Answer 1

1)     (270+57x10):14-85:17= (270+570):14 -5 = 840 : 14 - 5 = 60 - 5 = 55
2)     85- (36+2x17):14= 85-(36+34):14= 85-70:14 = 85-5 = 80
3)     1305:29-21x(36:6-5)=45-21x(6-5)=45-21x1=45-21=24

Answer 2

(270 + 57 * 10) : 14 - 85 : 17 = (270 + 570) : 14 - 5 = 840 : 14 - 5 = 60 - 5 = 55
85 - (36 + 2 * 17) : 14 = 85 - (36 + 34) : 14 = 85 - 70 : 14 = 85 - 5 = 80
1305 : 29 - 21 * (36 : 6 - 5) = 45 - 21 * (6 - 5) = 45 - 21 * 1 = 26
