Answer 1

(25:5+7×29):2+[230-(38×2×1+9)]
=(5+203):2+[230-(76×1+9)]
=208:2+[230-(76+9)]
=104+(230-85)
=104+145
=249

[(357:7+344:8):2]×31+17-(500:4+7)
=[(51+43):2]×31+17-(125+7)
=(94:2)×31+17-132
=47×31+17-132
=1457+17-132
=1474-132
=1342

(28×5+30):10+729:9-[25×(39-19×2)]
=(140+30):10+81-[25×(39-38)]
=170:10+81-(25×1)
=17+81-25
=98-25
=73

(57×2:3)+32×450-[39×(4+2):2]+8
=(114:3)+14400-(39×6:2)+8
=38+14400-(234:2)+8
=38+14400-117+8
=14438-117+8
=14321+8
=14329
