Rules for adding integers using the number line:
- Start at the First Number
Locate the first integer on the number line. - Move Based on the Second Number
- To add a positive integer, move to the right on the number line the number of units equal to the value of the second integer.
- To add a negative integer, move to the left on the number line the number of units equal to the absolute value of the second integer (the number without the negative sign).
- The Final Position:
The point where you stop is the sum.
Adding More Than Two Integers:
You can extend this process for adding more than two integers. For each integer in the sum, move right if it’s positive and left if it’s negative. The final position will be the sum.

Addition / Adding Integers by Using a Number Line
Using a number line is one way to think about what we are doing when adding / subtracting integers. It provides a nice visual representation of what we are doing.
Example:
Use a number line to add the following: 2 + (-6)
