00:03 Let's start from point (-10) on the negative (left) side of the axis
00:07 The number is directed and positive
00:10 The positive direction on the axis is to the right, so we'll go 3 to the right
00:19 And this is the solution to the question

Step-by-Step Solution

Let's first locate negative 10 on the number line.

Now let's handle the operation in the exercise, given that the operation is +3 +3

Since the number 3 is greater than 0, we will move three steps to the right from negative 10, where each step represents one whole number as follows:

-6-6-6-5-5-5-4-4-4-3-3-3-2-2-2-1-1-1000111222-7-7-7-8-8-8-9-9-9-10-10-10

We can see that the number we reached is negative 7.
