Solve 5 + (-2): Step-by-Step Number Line Solution

Question

$5+(-2)=$

00:00 Solve

00:06 The number is directed, and positive

00:13 The positive direction on the axis is rightward, so we'll take 5 to the right

00:17 The number is directed, and negative

00:21 The negative direction on the axis is leftward, so we'll take 2 to the left

00:31 And this is the solution to the question

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

Since the number 5 is greater than 0, we will 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 $+(-2)$

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

We can see that the number we reached is 3.

$3$
