In your own words tell how you can use the number line to add and subtract integers.

We can use number lines for adding as well as subtracting integers. For doing this:

1. First mark the first integer on the number line.

2. Now to add a positive integer to this number, move to the right on the number line from this number.

3. In case you have to add a negative integer, move to the left on the number line from this number.

4. Subtracting an integer means adding its opposite and hence, if you have to subtract a positive integer from this number, move to the left on the number line from this number.

5. But if you have to subtract a negative integer from this number, move to the right on the number line from this number.
