Let's solve the expression step by step:

\[
(7 - 5) + (13 - 4) - (17 + 3) + (18 - 9)
\]

1. Calculate each part inside the parentheses:
   - \( 7 - 5 = 2 \)
   - \( 13 - 4 = 9 \)
   - \( 17 + 3 = 20 \)
   - \( 18 - 9 = 9 \)

Now the expression becomes:

\[
2 + 9 - 20 + 9
\]

2. Perform the addition and subtraction:
   - \( 2 + 9 = 11 \)
   - \( 11 - 20 = -9 \)
   - \( -9 + 9 = 0 \)

So, the final result is:

\[
\boxed{0}
\]
