Let’s solve each math problem in the image step by step. We’ll calculate every expression and then compare it to π (pi), which is approximately 3.14.
We need to:
- Color grey if answer > 3.14
- Color orange if answer < 3.14
- Color green if answer = 3.14
But since we’re just solving the problems, let’s compute each one:
---
Top row:
1.
2 + 1
= 3 → less than 3.14 → orange
2.
3.60 - 0.55
= 3.05 → less than 3.14 → orange
3.
1.20 + 0.90
= 2.10 → less than 3.14 → orange
4.
8 - 4.50
= 3.50 → greater than 3.14 → grey
5.
6 - 4.80
= 1.20 → less than 3.14 → orange
---
Middle section (around “3”, “1”, “4”):
6.
1.75 + 0.25
= 2.00 → less than 3.14 → orange
7.
3.14 ÷ 2
= 1.57 → less than 3.14 → orange
8.
6 - 2.50
= 3.50 → greater than 3.14 → grey
9.
1.57 + 1.57
= 3.14 → equal to π → green
10.
7 - 3.86
= 3.14 → equal to π → green
11.
3.60 - 0.20
= 3.40 → greater than 3.14 → grey
---
Bottom left:
12.
2.20 + 1.30
= 3.50 → greater than 3.14 → grey
13.
1.15 + 1.99
= 3.14 → equal to π → green
14.
2.20 + 1.30 (again)
= 3.50 → greater than 3.14 → grey
15.
1.50 + 1.50
= 3.00 → less than 3.14 → orange
---
Bottom middle/right:
16.
4.2 + 1
= 5.2 → greater than 3.14 → grey
17.
4 - 0.95
= 3.05 → less than 3.14 → orange
18.
5.50 - 2.50
= 3.00 → less than 3.14 → orange
19.
0 + 3
= 3 → less than 3.14 → orange
20.
3.3 + 0.50
= 3.80 → greater than 3.14 → grey
21.
Circle with “5 - 1.86”
= 3.14 → equal to π → green

Now, let’s list all answers clearly for final reference:
| Problem | Answer | Compare to π (3.14) |
|------------------|--------|----------------------|
| 2 + 1 | 3 | < → orange |
| 3.60 - 0.55 | 3.05 | < → orange |
| 1.20 + 0.90 | 2.10 | < → orange |
| 8 - 4.50 | 3.50 | > → grey |
| 6 - 4.80 | 1.20 | < → orange |
| 1.75 + 0.25 | 2.00 | < → orange |
| 3.14 ÷ 2 | 1.57 | < → orange |
| 6 - 2.50 | 3.50 | > → grey |
| 1.57 + 1.57 | 3.14 | = → green |
| 7 - 3.86 | 3.14 | = → green |
| 3.60 - 0.20 | 3.40 | > → grey |
| 2.20 + 1.30 | 3.50 | > → grey |
| 1.15 + 1.99 | 3.14 | = → green |
| 2.20 + 1.30 | 3.50 | > → grey |
| 1.50 + 1.50 | 3.00 | < → orange |
| 4.2 + 1 | 5.2 | > → grey |
| 4 - 0.95 | 3.05 | < → orange |
| 5.50 - 2.50 | 3.00 | < → orange |
| 0 + 3 | 3 | < → orange |
| 3.3 + 0.50 | 3.80 | > → grey |
| 5 - 1.86 | 3.14 | = → green |
✔ All calculations checked twice — no errors found.
Final Answer:
All problems solved as above. Use the color key:
→ Grey if answer > 3.14
→ Orange if answer < 3.14
→ Green if answer = 3.14
