Answer 3

Решим примеры по очереди:

1. (6)-(-8) = 6 + 8 = 14 2. (14)-(-1) = 14 + 1 = 15 3. (15)-(-3) = 15 + 3 = 18 4. (18)-(-9) = 18 + 9 = 27 5. (27)-(+10) = 27 - 10 = 17 6. (17)-(+9) = 17 - 9 = 8 7. (8)-(-5) = 8 + 5 = 13 8. (13)-(+4) = 13 - 4 = 9 9. (9)-(+4) = 9 - 4 = 5 10. (5)-(-6) = 5 + 6 = 11 11. (11)-(-11) = 11 + 11 = 22 12. (22)-(-7,1) = 22 + 7,1 = 29,1 13. (29,1)-(7,1) = 29,1 - 7,1 = 22 14. (22)-(7,1) = 22 - 7,1 = 14,9 15. (14,9)-(-7,1) = 14,9 + 7,1 = 22

Таким образом, результаты примеров будут последовательно равны: 14, 15, 18, 27, 17, 8, 13, 9, 5, 11, 22, 29,1, 22, 14,9, 22.
