If the distance between point a and the origin on the number axis is 3, and the distance between point B and the origin is 5, then the distance between a and B is 0______ ．

If the distance from point a to the origin is 3, then a represents 3 or - 3; similarly, B represents 5 or - 5. Then the distance between a and B is 2 or 8
