Question

29. Calculează.
10 x 4:5x3 + 32 - 32:8 x 7 =
• 600 – 56 + 56 : 8 x 9 - 50: 5:10 x 3 =
100 - (42 + 42: 6 + 5x 3) =
(70 - 8 x 7): 2 + (21 + 21 : 3) =
340 - (100 – 100: 10 x 7 + 9 x 7) =
(80 - 6 x 9) (163 - 7 x 9) =
(100 - 28) : ( 45 - 36) + (4 x 8 + 9 x 5): 7 =

Răspuns:

31 604 36 35 247 2600 19

Explicație pas cu pas:

40:5x3+32-4x7=27+32-28=31

544+63-3=604

100-(42+7+15)=100-64=36

7+28=35

340-93=247

26x100=2600

72:9+11=8+11=19
