Solve 5 + (-6) Using Number Line Visualization

Let's locate the number 5 on the number line.

Since the number 5 is greater than 0, we'll move five steps to the right 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 $+(-6)$

And the number minus 6 is less than 0, we'll move six steps to the left from number 5, where each step represents one whole number as follows:

We can see that we reached the number minus 1.
