It looks like you've uploaded an image of a math worksheet titled
"Mixed Addition and Subtraction". The worksheet contains a series of arithmetic problems involving both addition and subtraction of three-digit numbers. There's also a space for the student's name and score, along with a colorful bird illustration.
Since I can't view images directly, I’ll help you solve this problem
if you provide the actual numbers from the worksheet or describe them. However, based on typical formats of such worksheets, here’s how we would approach solving it:
---
🔢 General Approach:
Each problem is likely structured like this:
```
345
+ 123
-----
```
or
```
345
- 123
-----
```
You need to perform either addition or subtraction for each pair.

✔ Step-by-step Solution Example:
Let’s assume one of the problems is:
```
345
+ 123
-----
```
Step 1: Add the ones place:
5 + 3 = 8
Step 2: Add the tens place:
4 + 2 = 6
Step 3: Add the hundreds place:
3 + 1 = 4
Answer: 468

Another example (subtraction):
```
345
- 123
-----
```
Step 1: Ones place: 5 - 3 = 2
Step 2: Tens place: 4 - 2 = 2
Step 3: Hundreds place: 3 - 1 = 2
Answer: 222

📝 How to Solve the Whole Worksheet:
For each problem:
1. Identify whether it's addition (+) or subtraction (−).
2. Line up the digits by place value (ones, tens, hundreds).
3. Perform the operation column by column.
4. Carry over or borrow if needed.

💡 Tips:
- Use
columnar alignment carefully.
- For subtraction, if the top digit is smaller than the bottom digit in a column,
borrow from the next higher place.
- Double-check your work!
