It is known that there are two points a and B on the number axis, the distance between a and B is 2, and the distance between a and origin 0 is 3, What is the sum of the distances between all the points B satisfying the conditions and the origin o

I'm glad to answer your question
Because the distance between a and origin 0 is 3
So a is 3 or - 3
Because the distance between a and B is 2
So B is
3-2=1,
3+2=5
-3-2=-5
-3+2=-1
So the sum of the distances between point B and origin o is [5 or 1]
