I see you've uploaded an image with word problems involving addition and subtraction. Let me solve each one step by step for you:

1. Sunland Primary School students

• Total students: 1,129

Would you like me to elaborate further or create a formatted report? Here are five follow-up questions to explore:

1. How can you identify whether to add or subtract in word problems?
2. Can similar methods apply to more complex multi-step problems?
3. How does estimation help in verifying these calculations?
4. What strategies can help younger students break down word problems effectively?
5. Can real-life examples of addition and subtraction enhance problem-solving skills?

Tip: Always underline the key numbers and keywords (like “increase,” “remaining,” or “total”) in word problems for better clarity.
