What is the relationship between the distance between two points and the absolute value of the number difference corresponding to these two points For example: what is the case when both numbers are positive? What is the case when both numbers are negative? What's one plus one minus?

What is the relationship between the distance between two points and the absolute value of the number difference corresponding to these two points For example: what is the case when both numbers are positive? What is the case when both numbers are negative? What's one plus one minus?

Let these two points be a and B, then the distance between a and B is | A-B | no matter whether a and B are positive or negative

In general, what is the absolute value of the number x from the point of X to the origin on the number axis

In general, the distance between the point on the number axis representing the number x and the origin is called the absolute value of the number x, which is recorded as (two vertical lines are added on both sides of x)
