🔢 Understanding the Examples:

#### Example 1: `4 + (-5) = -1`
- Start at 4 on the number line.
- Adding a negative number means you move left.
- Move 5 units left from 4 → lands on -1.

#### Example 2: `-2 + 2 = 0`
- Start at -2.
- Adding a positive number means you move right.
- Move 2 units right → lands on 0.

✔ So, the rule is:
> Adding a positive number → move RIGHT.
> Adding a negative number → move LEFT.
