170×10:17-85×2:5=

1700:17-85×2:5=

100-85×2:5=

100-170:5=

100-34=66

383+(1000-502):6=

383+498:6=

383+83=466

[472+51×4-(480:4+32×5)]×1000=

[472+51×4-(480:4+160)]×1000=

[472+51+×4-(120+160)]×1000=

(472+51×4-280)×1000=

(472+204-280)×1000=

(676-280)×1000=

396×1000=39600

3000-5×[41+(84-8×8:4):2]=

3000-5×[41+(84-64:4):2]=

3000-5×[41+(84-16):2]=

3000-5×(41+68:2)=

3000-5×(41+34)=

3000-5×75=

3000-375=2625
