Answer 1

Răspuns:

a) 24 + 38 - 12 = 50

62 - 12 = 50

56 - 24 + 27 = 59

32 + 27 = 59

3 × 3 - 0 = 9

9 - 0 = 9

b) 3 × 4 × 1 = 12

12 × 1 = 12

60 : 6 : 2 = 5

10 : 2 = 5

100 - 9 × 9 = 19

100 - 81 = 19

80 - 5 × 7 = 45

80 - 35 = 45

22 - 8 : 8 = 21

22 - 1 = 21

38 - 64 : 8 = 30

38 - 8 = 30

4 × 2 + 5 × 10 = 58

8 + 50 = 58

45 : 9 - 10 : 10 = 4

5 - 1 = 4

23 + 72 : 8 = 32

23 + 9 = 32
