🎨 Color Code Key:

- 20, 18 = green
- 16, 14 = red
- 12, 10 = blue
- 8, 6 = yellow
- 4, 2 = brown

✔ Step 1: Solve Each Addition Problem

We’ll go through all the addition expressions and compute their sums:

| Expression | Sum |
|----------|-----|
| 5+5 | 10 |
| 6+6 | 12 |
| 7+7 | 14 |
| 8+8 | 16 |
| 9+9 | 18 |
| 10+10 | 20 |
| 3+3 | 6 |
| 4+4 | 8 |
| 2+2 | 4 |
| 1+1 | 2 |

Now let’s assign colors based on the sums.

🌈 Step 2: Assign Colors Based on Sums

Using the key:

- 20, 18 → green
- 16, 14 → red
- 12, 10 → blue
- 8, 6 → yellow
- 4, 2 → brown

So:

| Sum | Color |
|-----|-----------|
| 20 | green |
| 18 | green |
| 16 | red |
| 14 | red |
| 12 | blue |
| 10 | blue |
| 8 | yellow |
| 6 | yellow |
| 4 | brown |
| 2 | brown |

🔍 Step 3: Apply Colors to Shapes

Now, go through each shape in the image and color it based on its sum:

#### 🔹 Green (20 or 18):
- 10+10 → 20 → green
- 9+9 → 18 → green

👉 All shapes with 10+10 or 9+9 should be colored green.

#### 🔴 Red (16 or 14):
- 8+8 → 16 → red
- 7+7 → 14 → red

👉 All 8+8 and 7+7 sections → red

#### 🔵 Blue (12 or 10):
- 6+6 → 12 → blue
- 5+5 → 10 → blue

👉 All 6+6 and 5+5 → blue

#### 🟡 Yellow (8 or 6):
- 4+4 → 8 → yellow
- 3+3 → 6 → yellow

👉 All 4+4 and 3+3 → yellow

#### 🟫 Brown (4 or 2):
- 2+2 → 4 → brown
- 1+1 → 2 → brown

👉 All 2+2 and 1+1 → brown

🧩 Final Coloring Guide:

| Expression | Color |
|------------|-----------|
| 10+10 | green |
| 9+9 | green |
| 8+8 | red |
| 7+7 | red |
| 6+6 | blue |
| 5+5 | blue |
| 4+4 | yellow |
| 3+3 | yellow |
| 2+2 | brown |
| 1+1 | brown |

🖼️ What Does It Look Like?

When you color all the shapes correctly, the pattern will form a symmetrical design, likely resembling a star or flower-like mosaic due to the repeating geometric shapes and symmetry.

The center has:
- 10+10 and 9+9 → green
- Surrounded by 8+8, 7+7 → red
- Then 6+6, 5+5 → blue
- Smaller sections like 3+3, 4+4 → yellow
- Bottom center: 2+2, 1+1 → brown

This creates a gradient-like effect from green (larger numbers) to brown (smaller numbers), forming a colorful mandala-style pattern.

✔ Summary of Solution:

1. Solve each addition problem.
2. Use the color code to assign colors.
3. Color each region accordingly.

> Final Answer:
> - Green: 10+10, 9+9
> - Red: 8+8, 7+7
> - Blue: 6+6, 5+5
> - Yellow: 4+4, 3+3
> - Brown: 2+2, 1+1

Once colored, the image will reveal a symmetrical, colorful design — possibly a flower or star — depending on how the shapes connect.
