Math worksheet on negative number addition and subtraction with examples and exercises.

Absolutely! Let’s solve Question 1 step by step. This is about adding and subtracting positive and negative numbers, which is a foundational skill in arithmetic.

---

## 📌 Key Rules to Remember:

1. Subtracting a larger number from a smaller one gives a negative result.
- Example: `2 - 3 = -1`

2. Adding a positive number to a negative number is like moving right on the number line from a negative starting point.
- Example: `-2 + 4 = 2`

3. Subtracting a positive number is the same as adding its negative.
- Example: `5 - 7 = 5 + (-7) = -2`

4. Two negatives in a row (like `- -`) become a positive, but here we mostly have subtraction or addition of negatives.
