Answer 2

Răspuns:

1) 2 × 8 + 2 × 19 + 2 × 1 = 56

1. 2 × 8 = 16

2. 2 × 19 = 38

3. 2 × 1 = 2

4. 16 + 38 = 54

5. 2 + 54 = 56

2) ( 10 + 18 ) : 2 + 2 × 52 = 118

1. 10 + 18 = 28

2. 2 × 52 = 104

3. 28 : 2 = 14

4. 104 + 14 = 118

3) ( 6 + 6 : 2 ) + 2 × 12 + 9 × 1 = 42

1. 6 : 2 = 3

2. 6 + 3 =9

3. 2 × 12 = 24

4. 9 × 1 = 9

5. 9 + 24 = 33

6. 33 + 9 = 42
