Answer 1

Răspuns:

(5+203):2+[230-76×1+9)]

208:2+(230-76×1+9)

104+(154+9)

104+153

[(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

(28×5+30):10+729:9-[25×(39-19×2)]

(140+30):10+729:9-[25×(39-38)]

170:10+729:9-(25×1)

17+81-25

123

(57×2:3)+32×450-[39×(4+2:2]+8

(114:3)+32×450-(39×5)+8

38+32×450-195+8

38+14400-195+8

38+11205+8

[(248:8-21×1):10]+(500:50+800:20)

[(31-21):10]+(10+40)

(10:10)+30

1+30

31

29×3-38+[2000-(17×2+39×1:3)]

29×3-28+[2000-(34+38×3)]

29×3-28+[2000-(34+114)]

29×3-28+(2000-148)

29×3-28+1852

87-28+1852
