Let's solve the expression \( 17 \frac{4}{9} + \frac{5}{9} - 8 - 10 \).
First, convert the mixed number \( 17 \frac{4}{9} \) to an improper fraction:
\[ 17 \frac{4}{9} = 17 + \frac{4}{9} = \frac{17 \times 9 + 4}{9} = \frac{153 + 4}{9} = \frac{157}{9} \]
Now add \( \frac{5}{9} \):
\[ \frac{157}{9} + \frac{5}{9} = \frac{157 + 5}{9} = \frac{162}{9} = 18 \]
Now subtract \( 8 \) and \( 10 \):
\[ 18 - 8 - 10 = 10 - 10 = 0 \]
Thus, the answer is:
\[ \boxed{0} \]
