Решение:
- (25 + 20) : 5
(25 + 20) : 5 = 45 : 5 = 9 - (5 + 7) : 4
(5 + 7) : 4 = 12 : 4 = 3 - 3,5 + 25
3,5 + 25 = 28,5 - 25 : 5 + 15
25 : 5 + 15 = 5 + 15 = 20 - (9 - 5) ⋅ 5
(9 - 5) ⋅ 5 = 4 ⋅ 5 = 20 - 20 : 4 - 2
20 : 4 - 2 = 5 - 2 = 3 - 20 : 5 + 1
20 : 5 + 1 = 4 + 1 = 5 - 40 : 5 + 17
40 : 5 + 17 = 8 + 17 = 25 - 63 : 9
63 : 9 = 7 - (73 + 8) : 9
(73 + 8) : 9 = 81 : 9 = 9
Ответ: 9, 3, 28,5, 20, 20, 3, 5, 25, 7, 9
