The task involves solving addition problems using visual representations of numbers. Each problem is depicted with colored circles (red and blue) that represent the numbers being added. The goal is to count the circles in each group, perform the addition, and write the result.

Step-by-Step Solution:

#### Problem 1:
- Visual Representation:
- Red circles: 4
- Blue circles: 5
- Addition: \( 4 + 5 \)
- Result: \( 9 \)

#### Problem 2:
- Visual Representation:
- Red circles: 3
- Blue circles: 6
- Addition: \( 3 + 6 \)
- Result: \( 9 \)

#### Problem 3:
- Visual Representation:
- Red circles: 7
- Blue circles: 2
- Addition: \( 7 + 2 \)
- Result: \( 9 \)

#### Problem 4:
- Visual Representation:
- Red circles: 5
- Blue circles: 4
- Addition: \( 5 + 4 \)
- Result: \( 9 \)

#### Problem 5:
- Visual Representation:
- Red circles: 6
- Blue circles: 3
- Addition: \( 6 + 3 \)
- Result: \( 9 \)

#### Problem 6:
- Visual Representation:
- Red circles: 8
- Blue circles: 1
- Addition: \( 8 + 1 \)
- Result: \( 9 \)

#### Problem 7:
- Visual Representation:
- Red circles: 2
- Blue circles: 7
- Addition: \( 2 + 7 \)
- Result: \( 9 \)

#### Problem 8:
- Visual Representation:
- Red circles: 3
- Blue circles: 6
- Addition: \( 3 + 6 \)
- Result: \( 9 \)

Final Answers:

1. \( 4 + 5 = 9 \)
2. \( 3 + 6 = 9 \)
3. \( 7 + 2 = 9 \)
4. \( 5 + 4 = 9 \)
5. \( 6 + 3 = 9 \)
6. \( 8 + 1 = 9 \)
7. \( 2 + 7 = 9 \)
8. \( 3 + 6 = 9 \)

Explanation:

Each problem uses a visual representation of numbers through colored circles. By counting the red and blue circles separately and then adding them together, we arrive at the sum. All the problems in this worksheet result in the same sum, which is 9.

Final Answer:

\[
\boxed{9}
\]
