To find the sum of $$ 69 + 18 $$, we can follow these steps:

1. **Align the numbers**: Write the numbers one below the other, aligning them by their rightmost digits.

```

   + 18
   ```

2. **Add the digits in the ones place**: 
   - The ones place has $$ 9 + 8 = 17 $$.
   - Write down $$ 7 $$ and carry over $$ 1 $$ to the next column.

3. **Add the digits in the tens place**:
   - The tens place has $$ 6 + 1 + 1 $$ (the carry) = $$ 8 $$.

4. **Combine the results**: 
   - The final sum is $$ 87 $$.

Thus, the sum of $$ 69 + 18 $$ is $$ 87 $$.
