Answer 1

Răspuns:

b) 5×5×10-(13+7×8) = 181

5×5×10-(13+56) =

5×5×10-69 =

25×10-69 =

250 - 69 =181

d) 8+(8×8:8-8)×5 = 8

8+(64:8-8)×5 =

8+(8-8)×5 =

8 + 0×5 =

8+0 = 8

f) (12+50:10)-6×2= 5

(12+5)-6×2=

17-12=5

h) 16-16:8+(16-16):8+99= 113

16-16:8+0:8+99=

16-2+0+99=

14+0+99=

14+99=113

j) 2×3×5+60:10:6-31 = 0

6×5+6:6-31 =

30+1-31 =

31-31 = 0

l) 45:5+54:6-(54+45):(4+5) = 7

45:5+54:6-99:9 =

9+9-11 =

18 - 11 = 7

n) 63+3×4-(2×2×2×2:8+5×6) = 43

63+3×4-(4×2×2:8+5×6) =

63+3×4-(8×2:8+5×6) =

63+3×4-(16:8+5×6) =

63+3×4-(2+30) =

63+3×4-32 =

63+12-32 =

75 - 32 = 43
