Answer 1

Răspuns:

1. 23+8:4 = 23+2 = 25

2.18-12:3 = 18-4 = 14

3.(63:9)x6 =7x6= 42

4. 37+(42:6)+17 = 37+7+17 = 44+17=61

5. 55-(45:9)-31 = 55-5-31 =50-31=19

6. (28:4)+(9x2) = 7+18=25

7. 15+[(18:3):2] = 15+(6:2) = 15+3 = 18

8. 24+[(42:7)x2] = 24+(6x2) = 24+12 = 36

9. 60-[(70:1)x0] = 60-(70x0) = 60
