The following diagram shows some examples of adding and subtracting using the number line. Scroll down the page for more examples and solutions on how to use the number line for adding and subtracting integers.
Method 1:
One way of using the number line for subtracting integers is to move in the opposite direction of adding integers.
To add a positive integer, move to
the right on the number line.
To add a negative integer, move to the left on the number line.
To subtract a positive integer, move to the left on the number line.
To subtract a negative integer, move to the right on the number line.
Examples:
5 - 2 =
-5 - 2 =
-4 - -7 =

How to think about adding and subtracting integers on a number line?
Use a happy and sad model.
Positive is happy side.
Negative is sad side.
Examples:
(+3) + (+2) =
(+3) + (-2) =
(+3) - (+2) =
(+3) - (-2) =

Method 2:
To subtract an integer, we can rewrite it as adding the opposite.
For eg.
3 − 2 = 3 + (−2)
3 − (−2) = 3 +
(+2)
Then, we use the number line the same way as in adding integers.
To add a positive integer, move to the right on the number line.
To add a negative integer, move to the left on the number line.
