Let’s solve the “Add or Subtract – Missing Symbol 2” worksheet step by step.
The task is to fill in either a
+ (plus) or
– (minus) sign between the two numbers so that the equation is correct.

We’ll go line by line:
---
✔ 1. 2 _ 5 = 7
- Try addition: 2 + 5 = 7 → ✔️ Correct!
- So, the missing symbol is
+
---
✔ 2. 7 _ 4 = 3
- Try addition: 7 + 4 = 11 → Too big.
- Try subtraction: 7 – 4 = 3 → ✔️ Correct!
- So, the missing symbol is
–
---
✔ 3. 2 _ 7 = 9
- Try addition: 2 + 7 = 9 → ✔️ Correct!
- So, the missing symbol is
+
---
✔ 4. 8 _ 3 = 5
- Try addition: 8 + 3 = 11 → Too big.
- Try subtraction: 8 – 3 = 5 → ✔️ Correct!
- So, the missing symbol is
–
---
✔ 5. 6 _ 3 = 9
- Try addition: 6 + 3 = 9 → ✔️ Correct!
- So, the missing symbol is
+
---
✔ 6. 7 _ 5 = 2
- Try addition: 7 + 5 = 12 → Too big.
- Try subtraction: 7 – 5 = 2 → ✔️ Correct!
- So, the missing symbol is
–
---
✔ 7. 3 _ 6 = 9
- Try addition: 3 + 6 = 9 → ✔️ Correct!
- So, the missing symbol is
+
---
✔ 8. 9 _ 8 = 1
- Try addition: 9 + 8 = 17 → Too big.
- Try subtraction: 9 – 8 = 1 → ✔️ Correct!
- So, the missing symbol is
–
---
✔ 9. 8 _ 2 = 6
- Try addition: 8 + 2 = 10 → Too big.
- Try subtraction: 8 – 2 = 6 → ✔️ Correct!
- So, the missing symbol is
–
---
✔ Final Answer (fill in the symbols):
```
2 + 5 = 7
7 - 4 = 3
2 + 7 = 9
8 - 3 = 5
6 + 3 = 9
7 - 5 = 2
3 + 6 = 9
9 - 8 = 1
8 - 2 = 6
```

🧠 Explanation Strategy:
To find the missing symbol:
-
If the result is larger than both numbers, you likely need
addition.
-
If the result is smaller than the first number, you likely need
subtraction.
- Always test both operations if unsure — only one will make the equation true!
This helps build number sense and understanding of how addition and subtraction relate to each other.
