On the number axis, point A is to the left of the origin, and point A represents the rational number a, so as to find the distance from point A to the origin. On the number axis, point A is to the left of the origin, and point A represents the rational number a.

Absolute value a

If a, b represents a rational number and a=-b, then the distance from the point representing the numbers a, b on the number axis to the origin is Is it the same distance?

You can see that the absolute values of AB are equal, and the absolute value is the distance from the point on the number axis to the origin
