Let's solve the expression $$ 4 + (4 + 4) + 5 \times 5 - 3^{2} $$ step by step, following the order of operations (parentheses, exponents, multiplication and division, addition and subtraction).

1. **Calculate the expression inside the parentheses**: 
   $$
   4 + 4 = 8
   $$

2. **Substitute back into the expression**:
   $$
   4 + 8 + 5 \times 5 - 3^{2}
   $$

3. **Calculate the exponent**:
   $$
   3^{2} = 9
   $$

4. **Substitute back into the expression**:
   $$
   4 + 8 + 5 \times 5 - 9
   $$

5. **Calculate the multiplication**:
   $$
   5 \times 5 = 25
   $$

6. **Substitute back into the expression**:
   $$
   4 + 8 + 25 - 9
   $$

7. **Now perform the addition and subtraction from left to right**:
   - First, $$ 4 + 8 = 12 $$
   - Then, $$ 12 + 25 = 37 $$
   - Finally, $$ 37 - 9 = 28 $$

Thus, the final result of the expression $$ 4 + (4 + 4) + 5 \times 5 - 3^{2} $$ is $$ 28 $$.
The result of the expression $$ 4 + (4 + 4) + 5 \times 5 - 3^{2} $$ is $$ 28 $$.
