To solve the expression \( 17 \frac{4}{9} + \frac{5}{9} - 8 - 10 \), we can simplify it step by step.
1. **Convert mixed number to an improper fraction:**
\[
17 \frac{4}{9} = \frac{17 \times 9 + 4}{9} = \frac{153 + 4}{9} = \frac{157}{9}
\]
2. **Combine fractions:**
Now, add \( \frac{5}{9} \) to \( \frac{157}{9} \):
\[
\frac{157}{9} + \frac{5}{9} = \frac{157 + 5}{9} = \frac{162}{9} = 18
\]
3. **Combine with the other numbers:**
Now, subtract \( 8 \) and then \( 10 \):
\[
18 - 8 - 10 = 18 - 18 = 0
\]
Thus, the final result is:
\[
\boxed{0}
\]
