Step-by-step solution for: Addition & Subtraction (0-20) - Color by Code / Coloring Pages ...
Let's solve this fun math coloring worksheet step by step.
- Solve each addition and subtraction problem in the image.
- Write the answer for each problem.
- Use the color key at the bottom to determine which color to use for each answer.
- Then, color the corresponding sections of the dragon picture.

Here’s the color code:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5
> Note: There's a typo in the key — YELLOW says "2, 5", but ORANGE also includes "5". So likely, YELLOW should be 2, and ORANGE is 5, 10. But since it's written as:
>
> - YELLOW → 2, 5
> - ORANGE → 5, 10
>
> That means 5 appears in both. This could be a mistake. But let's assume:
> - YELLOW: 2 only (maybe "5" is a typo)
> - ORANGE: 5, 10
> - RED: 1, 7
> - BLUE: 4, 8
> - GREEN: 6, 9
>
> But wait — YELLOW says "2, 5", so perhaps 5 can be either yellow or orange? That’s ambiguous.
But looking closely: The key shows:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5
So 5 appears in both ORANGE and YELLOW — that's inconsistent. Likely, YELLOW should be 2 only, and ORANGE is 5, 10. Or maybe YELLOW is 2, and ORANGE is 5, 10, and 5 is shared? That doesn’t make sense.
But perhaps the intention is:
- YELLOW: answers that are 2 or 5
- ORANGE: answers that are 5 or 10
That would mean 5 gets colored both yellow and orange? That’s not possible.
Wait — probably a typo. Let’s assume:
- YELLOW: 2
- ORANGE: 5, 10
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
But the key says YELLOW → 2, 5, so maybe 5 is yellow, and 10 is orange.
So let’s go with:
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
- ORANGE: 10
- YELLOW: 2, 5
Yes — that makes more sense. Probably ORANGE was meant to be 10 only, and YELLOW is 2 and 5.
But the key says:
> ORANGE → 5, 10
> YELLOW → 2, 5
So 5 is in both. That’s confusing.
Wait — maybe it's a mistake, and ORANGE should be 10, and YELLOW is 2, 5.
But let's just proceed carefully.
We'll solve all problems first, then assign colors based on the numbers.

Let’s list all the problems and their answers:
1. 3 - 1 = → 2
2. 6 + 4 = → 10
3. 10 - 5 = → 5
4. 8 - 2 = → 6
5. 6 + 1 = → 7
6. 5 - 1 = → 4
7. 10 - 3 = → 7
8. 2 + 4 = → 6
9. 9 - 3 = → 6
10. 4 + 3 = → 7
11. 7 - 1 = → 6
12. 1 + 3 = → 4
13. 5 + 2 = → 7
14. 6 + 4 = → 10
15. 10 - 0 = → 10
16. 4 + 2 = → 6
17. 3 + 5 = → 8
18. 2 + 3 = → 5
19. 9 + 0 = → 9
20. 1 - 0 = → 1
21. 8 + 0 = → 8
22. 5 + 2 = → 7
23. 10 - 3 = → 7
24. 6 - 4 = → 2
25. 6 + 4 = → 10
26. 10 - 0 = → 10
27. 5 + 2 = → 7
28. 4 + 3 = → 7
29. 10 - 3 = → 7
30. 2 + 4 = → 6
31. 3 + 5 = → 8
32. 2 + 3 = → 5
33. 9 + 0 = → 9
34. 1 - 0 = → 1
Wait — some are repeated. Let’s list them uniquely from the image:
From the image:
- 3 - 1 = 2
- 6 + 4 = 10
- 10 - 5 = 5
- 8 - 2 = 6
- 6 + 1 = 7
- 5 - 1 = 4
- 10 - 3 = 7
- 2 + 4 = 6
- 9 - 3 = 6
- 4 + 3 = 7
- 7 - 1 = 6
- 1 + 3 = 4
- 5 + 2 = 7
- 6 + 4 = 10
- 10 - 0 = 10
- 4 + 2 = 6
- 3 + 5 = 8
- 2 + 3 = 5
- 9 + 0 = 9
- 1 - 0 = 1
- 8 + 0 = 8
- 5 + 2 = 7
- 10 - 3 = 7
- 6 - 4 = 2
- 6 + 4 = 10
- 10 - 0 = 10
- 5 + 2 = 7
- 4 + 3 = 7
- 10 - 3 = 7
- 2 + 4 = 6
- 3 + 5 = 8
- 2 + 3 = 5
- 9 + 0 = 9
- 1 - 0 = 1
Now, collect all unique answers and their frequencies:
| Answer | Count |
|--------|-------|
| 1 | 2 |
| 2 | 2 |
| 4 | 2 |
| 5 | 3 |
| 6 | 6 |
| 7 | 7 |
| 8 | 2 |
| 9 | 2 |
| 10 | 4 |
Now apply the color key:
Use the key:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5
But now we see:
- 5 appears in both ORANGE and YELLOW — conflict!
Likely, YELLOW should be 2 only, and ORANGE is 5, 10.
But the key says YELLOW → 2, 5, so perhaps:
- 5 is colored YELLOW
- 10 is colored ORANGE
And 5 is only in one color — so maybe the key intends:
- YELLOW: 2, 5
- ORANGE: 10
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
Then:
- 1 → RED
- 2 → YELLOW
- 4 → BLUE
- 5 → YELLOW
- 6 → GREEN
- 7 → RED
- 8 → BLUE
- 9 → GREEN
- 10 → ORANGE
This avoids overlap.
So final color mapping:
| Answer | Color |
|--------|----------|
| 1 | RED |
| 2 | YELLOW |
| 4 | BLUE |
| 5 | YELLOW |
| 6 | GREEN |
| 7 | RED |
| 8 | BLUE |
| 9 | GREEN |
| 10 | ORANGE |
---
Now, go through each problem and color accordingly:
1. 3 - 1 = 2 → YELLOW
2. 6 + 4 = 10 → ORANGE
3. 10 - 5 = 5 → YELLOW
4. 8 - 2 = 6 → GREEN
5. 6 + 1 = 7 → RED
6. 5 - 1 = 4 → BLUE
7. 10 - 3 = 7 → RED
8. 2 + 4 = 6 → GREEN
9. 9 - 3 = 6 → GREEN
10. 4 + 3 = 7 → RED
11. 7 - 1 = 6 → GREEN
12. 1 + 3 = 4 → BLUE
13. 5 + 2 = 7 → RED
14. 6 + 4 = 10 → ORANGE
15. 10 - 0 = 10 → ORANGE
16. 4 + 2 = 6 → GREEN
17. 3 + 5 = 8 → BLUE
18. 2 + 3 = 5 → YELLOW
19. 9 + 0 = 9 → GREEN
20. 1 - 0 = 1 → RED
21. 8 + 0 = 8 → BLUE
22. 5 + 2 = 7 → RED
23. 10 - 3 = 7 → RED
24. 6 - 4 = 2 → YELLOW
25. 6 + 4 = 10 → ORANGE
26. 10 - 0 = 10 → ORANGE
27. 5 + 2 = 7 → RED
28. 4 + 3 = 7 → RED
29. 10 - 3 = 7 → RED
30. 2 + 4 = 6 → GREEN
31. 3 + 5 = 8 → BLUE
32. 2 + 3 = 5 → YELLOW
33. 9 + 0 = 9 → GREEN
34. 1 - 0 = 1 → RED
---
Now, when you color the dragon:
- Any section with answer = 1 or 7 → RED
- Any section with answer = 4 or 8 → BLUE
- Any section with answer = 6 or 9 → GREEN
- Any section with answer = 5 → YELLOW
- Any section with answer = 10 → ORANGE
Note: Since 5 is in YELLOW, and 10 in ORANGE, no conflict.

After solving each problem, color each section according to the answer and the key.
You’ll end up with a colorful dragon!
✔ Done!
Step 1: Understand the Task
- Solve each addition and subtraction problem in the image.
- Write the answer for each problem.
- Use the color key at the bottom to determine which color to use for each answer.
- Then, color the corresponding sections of the dragon picture.

Step 2: Color Key
Here’s the color code:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5
> Note: There's a typo in the key — YELLOW says "2, 5", but ORANGE also includes "5". So likely, YELLOW should be 2, and ORANGE is 5, 10. But since it's written as:
>
> - YELLOW → 2, 5

> That means 5 appears in both. This could be a mistake. But let's assume:
> - YELLOW: 2 only (maybe "5" is a typo)

> But wait — YELLOW says "2, 5", so perhaps 5 can be either yellow or orange? That’s ambiguous.
But looking closely: The key shows:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5
So 5 appears in both ORANGE and YELLOW — that's inconsistent. Likely, YELLOW should be 2 only, and ORANGE is 5, 10. Or maybe YELLOW is 2, and ORANGE is 5, 10, and 5 is shared? That doesn’t make sense.
But perhaps the intention is:
- YELLOW: answers that are 2 or 5
- ORANGE: answers that are 5 or 10
That would mean 5 gets colored both yellow and orange? That’s not possible.
Wait — probably a typo. Let’s assume:
- YELLOW: 2
- ORANGE: 5, 10
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
But the key says YELLOW → 2, 5, so maybe 5 is yellow, and 10 is orange.
So let’s go with:
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
- ORANGE: 10
- YELLOW: 2, 5
Yes — that makes more sense. Probably ORANGE was meant to be 10 only, and YELLOW is 2 and 5.
But the key says:
> ORANGE → 5, 10
> YELLOW → 2, 5
So 5 is in both. That’s confusing.
Wait — maybe it's a mistake, and ORANGE should be 10, and YELLOW is 2, 5.
But let's just proceed carefully.
We'll solve all problems first, then assign colors based on the numbers.

Step 3: Solve Each Problem
Let’s list all the problems and their answers:
1. 3 - 1 = → 2
2. 6 + 4 = → 10
3. 10 - 5 = → 5
4. 8 - 2 = → 6
5. 6 + 1 = → 7
6. 5 - 1 = → 4
7. 10 - 3 = → 7
8. 2 + 4 = → 6
9. 9 - 3 = → 6
10. 4 + 3 = → 7
11. 7 - 1 = → 6
12. 1 + 3 = → 4
13. 5 + 2 = → 7
14. 6 + 4 = → 10
15. 10 - 0 = → 10
16. 4 + 2 = → 6
17. 3 + 5 = → 8
18. 2 + 3 = → 5
19. 9 + 0 = → 9
20. 1 - 0 = → 1
21. 8 + 0 = → 8
22. 5 + 2 = → 7
23. 10 - 3 = → 7
24. 6 - 4 = → 2
25. 6 + 4 = → 10
26. 10 - 0 = → 10
27. 5 + 2 = → 7
28. 4 + 3 = → 7
29. 10 - 3 = → 7
30. 2 + 4 = → 6
31. 3 + 5 = → 8
32. 2 + 3 = → 5
33. 9 + 0 = → 9
34. 1 - 0 = → 1
Wait — some are repeated. Let’s list them uniquely from the image:
From the image:
- 3 - 1 = 2
- 6 + 4 = 10
- 10 - 5 = 5
- 8 - 2 = 6
- 6 + 1 = 7
- 5 - 1 = 4
- 10 - 3 = 7
- 2 + 4 = 6
- 9 - 3 = 6
- 4 + 3 = 7
- 7 - 1 = 6
- 1 + 3 = 4
- 5 + 2 = 7
- 6 + 4 = 10
- 10 - 0 = 10
- 4 + 2 = 6
- 3 + 5 = 8
- 2 + 3 = 5
- 9 + 0 = 9
- 1 - 0 = 1
- 8 + 0 = 8
- 5 + 2 = 7
- 10 - 3 = 7
- 6 - 4 = 2
- 6 + 4 = 10
- 10 - 0 = 10
- 5 + 2 = 7
- 4 + 3 = 7
- 10 - 3 = 7
- 2 + 4 = 6
- 3 + 5 = 8
- 2 + 3 = 5
- 9 + 0 = 9
- 1 - 0 = 1
Now, collect all unique answers and their frequencies:
| Answer | Count |
|--------|-------|
| 1 | 2 |
| 2 | 2 |
| 4 | 2 |
| 5 | 3 |
| 6 | 6 |
| 7 | 7 |
| 8 | 2 |
| 9 | 2 |
| 10 | 4 |
Now apply the color key:
Color Assignment Based on Answers
Use the key:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5
But now we see:
- 5 appears in both ORANGE and YELLOW — conflict!
Likely, YELLOW should be 2 only, and ORANGE is 5, 10.
But the key says YELLOW → 2, 5, so perhaps:
- 5 is colored YELLOW
- 10 is colored ORANGE
And 5 is only in one color — so maybe the key intends:
- YELLOW: 2, 5
- ORANGE: 10
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
Then:
- 1 → RED
- 2 → YELLOW
- 4 → BLUE
- 5 → YELLOW
- 6 → GREEN
- 7 → RED
- 8 → BLUE
- 9 → GREEN
- 10 → ORANGE
This avoids overlap.
So final color mapping:
| Answer | Color |
|--------|----------|
| 1 | RED |
| 2 | YELLOW |
| 4 | BLUE |
| 5 | YELLOW |
| 6 | GREEN |
| 7 | RED |
| 8 | BLUE |
| 9 | GREEN |
| 10 | ORANGE |

Step 4: Assign Colors to Each Section
Now, go through each problem and color accordingly:
1. 3 - 1 = 2 → YELLOW
2. 6 + 4 = 10 → ORANGE
3. 10 - 5 = 5 → YELLOW
4. 8 - 2 = 6 → GREEN
5. 6 + 1 = 7 → RED
6. 5 - 1 = 4 → BLUE
7. 10 - 3 = 7 → RED
8. 2 + 4 = 6 → GREEN
9. 9 - 3 = 6 → GREEN
10. 4 + 3 = 7 → RED
11. 7 - 1 = 6 → GREEN
12. 1 + 3 = 4 → BLUE
13. 5 + 2 = 7 → RED
14. 6 + 4 = 10 → ORANGE
15. 10 - 0 = 10 → ORANGE
16. 4 + 2 = 6 → GREEN
17. 3 + 5 = 8 → BLUE
18. 2 + 3 = 5 → YELLOW
19. 9 + 0 = 9 → GREEN
20. 1 - 0 = 1 → RED
21. 8 + 0 = 8 → BLUE
22. 5 + 2 = 7 → RED
23. 10 - 3 = 7 → RED
24. 6 - 4 = 2 → YELLOW
25. 6 + 4 = 10 → ORANGE
26. 10 - 0 = 10 → ORANGE
27. 5 + 2 = 7 → RED
28. 4 + 3 = 7 → RED
29. 10 - 3 = 7 → RED
30. 2 + 4 = 6 → GREEN
31. 3 + 5 = 8 → BLUE
32. 2 + 3 = 5 → YELLOW
33. 9 + 0 = 9 → GREEN
34. 1 - 0 = 1 → RED

Final Coloring Instructions
Now, when you color the dragon:
- Any section with answer = 1 or 7 → RED
- Any section with answer = 4 or 8 → BLUE
- Any section with answer = 6 or 9 → GREEN
- Any section with answer = 5 → YELLOW
- Any section with answer = 10 → ORANGE
Note: Since 5 is in YELLOW, and 10 in ORANGE, no conflict.
