🔍 Understanding the Worksheet

#### Set A: [3-2, 3-1, 4-3, 4-1]
This means the core subtraction facts to focus on are:
- 3 − 2 = 1
- 3 − 1 = 2
- 4 − 3 = 1
- 4 − 1 = 3

These are the foundational problems that appear repeatedly in the worksheet.

🔢 Part 1: Practice on facts in Set A

Each row contains simple subtraction problems. Let's solve them:

#### Row 1:
```
3 -1 = 2 4 -1 = 3 4 -3 = 1 4 -1 = 3 3 -2 = 1 4 -1 = 3 3 -1 = 2 4 -3 = 1 3 -2 = 1 4 -1 = 3
```

#### Row 2:
```
4 -3 = 1 3 -1 = 2 4 -1 = 3 3 -1 = 2 4 -3 = 1 3 -2 = 1 4 -1 = 3 3 -1 = 2 3 -2 = 1 4 -3 = 1
```

#### Row 3:
```
3 -1 = 2 4 -3 = 1 3 -1 = 2 3 -2 = 1 4 -3 = 1 4 -1 = 3 3 -1 = 2 3 -2 = 1 3 -1 = 2 4 -1 = 3
```

#### Row 4:
```
4 -1 = 3 3 -2 = 1 4 -3 = 1 4 -1 = 3 4 -3 = 1 3 -2 = 1 4 -3 = 1 3 -2 = 1 3 -1 = 2 3 -2 = 1
```

⏱️ Part 2: One Minute Timing on facts in Set A

This section has more problems for speed practice. We'll solve them similarly.

#### Row 1:
```
3 -2 = 1 3 -1 = 2 4 -3 = 1 3 -1 = 2 3 -2 = 1 4 -3 = 1 4 -1 = 3 3 -1 = 2 3 -2 = 1 3 -1 = 2
```

#### Row 2:
```
4 -1 = 3 3 -2 = 1 3 -1 = 2 4 -1 = 3 4 -3 = 1 4 -1 = 3 3 -1 = 2 3 -2 = 1 3 -1 = 2 4 -3 = 1
```

#### Row 3:
```
3 -1 = 2 4 -1 = 3 4 -3 = 1 4 -1 = 3 3 -1 = 2 3 -2 = 1 3 -1 = 2 4 -3 = 1 3 -2 = 1 4 -1 = 3
```

#### Row 4:
```
4 -1 = 3 4 -3 = 1 3 -2 = 1 4 -1 = 3 4 -3 = 1 3 -2 = 1 4 -1 = 3 4 -1 = 3 3 -2 = 1 4 -3 = 1
```

📊 Summary of All Answers

All problems follow the same pattern. Here’s a quick reference table for the facts:

| Problem | Answer |
|--------|--------|
| 3 - 1 | 2 |
| 3 - 2 | 1 |
| 4 - 1 | 3 |
| 4 - 3 | 1 |

Every problem in this worksheet uses one of these four facts.
