Problem Description:

The image shows a grid of addition problems. Each cell contains two numbers to be added together. The task is to solve each addition problem and provide the correct sums.

Solution Approach:

1. Identify Each Addition Problem: Each cell in the grid contains two numbers separated by a plus sign (+).
2. Perform the Addition: Add the two numbers in each cell.
3. Record the Results: Write down the sum for each addition problem.

Step-by-Step Solution:

#### Row 1:
- \( 9 + 2 = 11 \)
- \( 6 + 3 = 9 \)
- \( 8 + 4 = 12 \)
- \( 5 + 5 = 10 \)
- \( 7 + 6 = 13 \)

#### Row 2:
- \( 4 + 7 = 11 \)
- \( 2 + 8 = 10 \)
- \( 3 + 9 = 12 \)
- \( 1 + 8 = 9 \)
- \( 9 + 8 = 17 \)

#### Row 3:
- \( 8 + 8 = 16 \)
- \( 7 + 8 = 15 \)
- \( 6 + 8 = 14 \)
- \( 5 + 6 = 11 \)
- \( 4 + 5 = 9 \)

#### Row 4:
- \( 3 + 4 = 7 \)
- \( 2 + 3 = 5 \)
- \( 1 + 2 = 3 \)
- \( 7 + 5 = 12 \)
- \( 7 + 4 = 11 \)

#### Row 5:
- \( 7 + 3 = 10 \)
- \( 7 + 2 = 9 \)
- \( 6 + 5 = 11 \)
- \( 6 + 4 = 10 \)
- \( 6 + 3 = 9 \)

#### Row 6:
- \( 6 + 2 = 8 \)
- \( 5 + 4 = 9 \)
- \( 5 + 3 = 8 \)
- \( 4 + 3 = 7 \)
- \( 4 + 2 = 6 \)

Final Answer:

The completed grid with all sums is as follows:

\[
\begin{array}{|c|c|c|c|c|}
\hline
11 & 9 & 12 & 10 & 13 \\
\hline
11 & 10 & 12 & 9 & 17 \\
\hline
16 & 15 & 14 & 11 & 9 \\
\hline
7 & 5 & 3 & 12 & 11 \\
\hline
10 & 9 & 11 & 10 & 9 \\
\hline
8 & 9 & 8 & 7 & 6 \\
\hline
\end{array}
\]

\boxed{
\begin{array}{|c|c|c|c|c|}
\hline
11 & 9 & 12 & 10 & 13 \\
\hline
11 & 10 & 12 & 9 & 17 \\
\hline
16 & 15 & 14 & 11 & 9 \\
\hline
7 & 5 & 3 & 12 & 11 \\
\hline
10 & 9 & 11 & 10 & 9 \\
\hline
8 & 9 & 8 & 7 & 6 \\
\hline
\end{array}
