Выполним вычисления:

• 9 ⋅ 5 = 45


• 56 ∶ 8 = 7


• 42 ∶ (6 ⋅ 9) = 42 ∶ 54 = 7/9


• 4 ⋅ 9 = 36


• 54 ∶ 9 = 6


• 32 ∶ (8 ⋅ 3) = 32 ∶ 24 = 4/3


• 6 - 7 = -1


• 49 ∶ 7 = 7


• 27 ∶ (3 ⋅ 6) = 27 ∶ 18 = 3/2


• 8 ⋅ (20 - 14) = 8 ⋅ 6 = 48


• (36 + 12) ∶ 6 = 48 ∶ 6 = 8


• (90 - 42) ∶ 8 = 48 ∶ 8 = 6
