On positive and negative numbers in the first day of junior high school There are two points a and B on the vertical axis. The distance between a and B is 1, and the distance between a and origin 0 is 3. Find the sum of the distances between B and origin that meet the conditions? (Note: the distance in the question can be positive or negative.) The wrong type is the number axis, not the vertical axis

Point may be
a. (0,3), and the coordinates of point B are (0,2) or (0,4)
b. (0, - 3), and the coordinates of point B are (0, - 2) or (0, - 4)
c. (3,0), and the coordinates of point B are (2,0) or (4,0)
d. (- 3,0), then the coordinates of point B are (- 2,0) or (- 4,0)
Then 2 + 4 + 2 + 4 + 2 + 4 + 2 + 4 = 24
The sum of distances between all points B satisfying the condition and the origin is 24
