Adding Negative Numbers: Solve (-5) + (-2) Using Number Line

Let's locate negative 5 on the number line.

Since negative 5 is less than 0, we'll move five steps to the left from zero, where each step represents one whole number as follows:

Now let's look at the operation in the exercise.

Since the operation is $+(-2)$

And negative 2 is less than 0, we'll move two steps to the left from negative 5, where each step represents one whole number as follows:

We can see that we reached negative 7.
