🔹 Understanding the Number Line

The number line shows integers from -5 to 5.
- Moving right means adding.
- Moving left means subtracting.

For example:
- To do `2 - 3`: Start at 2, move 3 steps left → land on -1.

📌 Key Tips:

- Subtracting a positive number: Move left on the number line.
- Adding a positive number: Move right.
- Negative numbers are less than zero, so moving left goes into negatives.
- When you add or subtract, always start at the first number and move accordingly.
