It seems you've uploaded an image containing a worksheet for practicing mixed addition and subtraction problems. Since the image itself isn't directly visible in this format, I'll provide a general explanation of how to solve such problems and then demonstrate with examples similar to what might be on the worksheet.
General Approach to Solving Mixed Addition and Subtraction Problems:
1.
Identify the Operation: Look at each problem to determine whether it involves addition (+) or subtraction (−).
2.
Perform the Calculation:
- For addition: Add the numbers together.
- For subtraction: Subtract the second number from the first.
3.
Write Down the Answer: Ensure your answer is clear and correct.
