Problem Description:
The image shows three worksheets titled "Addition and Subtraction Facts." Each worksheet focuses on different ranges of numbers:
1.
Worksheet 1: Addition and Subtraction Facts to 50.
2.
Worksheet 2: Addition and Subtraction Facts to 100.
3.
Worksheet 3: Addition and Subtraction Facts to 1000.
Each worksheet contains a grid of problems involving addition and subtraction. The task is to solve the problems in each worksheet.
---
Solution Approach:
To solve the problems, we will:
1. Identify the range of numbers for each worksheet.
2. Solve the addition and subtraction problems systematically.
3. Provide examples for each worksheet to illustrate the process.

Worksheet 1: Addition and Subtraction Facts to 50
#### Example Problems:
-
Addition: \( 23 + 8 \)
- Add the numbers: \( 23 + 8 = 31 \)
-
Subtraction: \( 45 - 7 \)
- Subtract the numbers: \( 45 - 7 = 38 \)
#### General Process:
- For addition, combine the two numbers.
- For subtraction, take the second number away from the first.

Worksheet 2: Addition and Subtraction Facts to 100
#### Example Problems:
-
Addition: \( 67 + 25 \)
- Add the numbers: \( 67 + 25 = 92 \)
-
Subtraction: \( 89 - 34 \)
- Subtract the numbers: \( 89 - 34 = 55 \)
#### General Process:
- Perform standard addition or subtraction, ensuring to carry over or borrow as needed.

Worksheet 3: Addition and Subtraction Facts to 1000
#### Example Problems:
-
Addition: \( 456 + 321 \)
- Add the numbers: \( 456 + 321 = 777 \)
-
Subtraction: \( 890 - 234 \)
- Subtract the numbers: \( 890 - 234 = 656 \)
#### General Process:
- Align the numbers by place value (ones, tens, hundreds).
- Perform addition or subtraction, carrying over or borrowing as necessary.

Final Answer:
Since the problem does not specify which specific problems to solve, the general approach is outlined above. If you need solutions for specific problems, please provide the exact problems, and I can solve them step-by-step.
For now, the
general solution is:
\[
\boxed{\text{Solve each addition and subtraction problem by following the standard arithmetic rules for the given range.}}
\]
