Problem Description:

The image contains a series of addition problems. Each problem consists of two numbers, and the task is to solve each addition problem by finding the sum.

Solution Approach:

We will solve each addition problem step by step. The general formula for addition is:
\[
\text{Sum} = \text{First Number} + \text{Second Number}
\]

Step-by-Step Solution:

#### Row 1:
1. \( 1 + 0 = 1 \)
2. \( 4 + 2 = 6 \)
3. \( 6 + 3 = 9 \)
4. \( 8 + 2 = 10 \)

#### Row 2:
1. \( 5 + 2 = 7 \)
2. \( 3 + 1 = 4 \)
3. \( 7 + 3 = 10 \)
4. \( 2 + 1 = 3 \)

#### Row 3:
1. \( 4 + 3 = 7 \)
2. \( 6 + 4 = 10 \)
3. \( 9 + 0 = 9 \)
4. \( 2 + 2 = 4 \)

#### Row 4:
1. \( 6 + 0 = 6 \)
2. \( 3 + 3 = 6 \)
3. \( 8 + 1 = 9 \)
4. \( 5 + 5 = 10 \)

#### Row 5:
1. \( 7 + 2 = 9 \)
2. \( 4 + 4 = 8 \)
3. \( 9 + 1 = 10 \)
4. \( 5 + 4 = 9 \)

Final Answers:

Combining all the results, we get:
\[
\begin{aligned}
&\text{Row 1: } 1, 6, 9, 10 \\
&\text{Row 2: } 7, 4, 10, 3 \\
&\text{Row 3: } 7, 10, 9, 4 \\
&\text{Row 4: } 6, 6, 9, 10 \\
&\text{Row 5: } 9, 8, 10, 9
\end{aligned}
\]

Boxed Final Answer:

\[
\boxed{1, 6, 9, 10, 7, 4, 10, 3, 7, 10, 9, 4, 6, 6, 9, 10, 9, 8, 10, 9}
\]
