Ответ:
Возможные выражения:
- 1 + 14 = 15
- 2 + 13 = 15
- 3 + 12 = 15
- 4 + 11 = 15
- 5 + 10 = 15
- 6 + 9 = 15
- 7 + 8 = 15
- 8 + 7 = 15
- 9 + 6 = 15
- 10 + 5 = 15
- 11 + 4 = 15
- 12 + 3 = 15
- 13 + 2 = 15
- 14 + 1 = 15
- 15 − 1 = 14
- 15 − 2 = 13
- 15 − 3 = 12
- 15 − 4 = 11
- 15 − 5 = 10
- 15 − 6 = 9
- 15 − 7 = 8
- 15 − 8 = 7
- 15 − 9 = 6
- 15 − 10 = 5
Ответ: например, 1 + 14 = 15, 2 + 13 = 15, 3 + 12 = 15, 4 + 11 = 15, 5 + 10 = 15, 6 + 9 = 15, 7 + 8 = 15.
