6.9.5 56:8 42:6.9 8.(20-14) 4.9 54:9 32:8.3 (36+12): 6 6-7 49:7 27:3.6 (90-42):8

1. 9 ⋅ 5 = 45


2. 56 : 8 = 7


3. 42 : 6 ⋅ 9 = 7 ⋅ 9 = 63


4. 8 ⋅ (20 - 14) = 8 ⋅ 6 = 48


5. 4 ⋅ 9 = 36


6. 54 : 9 = 6


7. 32 : 8 ⋅ 3 = 4 ⋅ 3 = 12


8. (36 + 12) : 6 = 48 : 6 = 8


9. 6 - 7 = -1


10. 49 : 7 = 7


11. 27 : 3 ⋅ 6 = 9 ⋅ 6 = 54


12. (90 - 42) : 8 = 48 : 8 = 6
