Let's simplify the expression step by step:

1. Start by calculating the sum of the first part:
\(1 + 1 + 2 + 3 - 4 + 1 - 3 + 3 + 2 - 1 + 6 - 8 + 9\)

- Calculate the sums in sequences:
- \(1 + 1 = 2\)
- \(2 + 2 = 4\)
- \(4 + 3 = 7\)
- \(7 - 4 = 3\)
- \(3 + 1 = 4\)
- \(4 - 3 = 1\)
- \(1 + 3 = 4\)
- \(4 + 2 = 6\)
- \(6 - 1 = 5\)
- \(5 + 6 = 11\)
- \(11 - 8 = 3\)
- \(3 + 9 = 12\)

So, the total for the first part is \(12\).

2. Now calculate the second part:
\(1 + 2 + 3 - 4 + 1 - 3 + 3 + 2 - 1 + 6 - 8 + 9 - 9\)

- Calculate this one similarly:
- \(1 + 2 = 3\)
- \(3 + 3 = 6\)
- \(6 - 4 = 2\)
- \(2 + 1 = 3\)
- \(3 - 3 = 0\)
- \(0 + 3 = 3\)
- \(3 + 2 = 5\)
- \(5 - 1 = 4\)
- \(4 + 6 = 10\)
- \(10 - 8 = 2\)
- \(2 + 9 = 11\)
- \(11 - 9 = 2\)

So, the total for the second part is \(2\).

3. Finally, add the results:
\(12 + 2 = 14\)

Therefore, the final result is \(14\).
