Ramses then continued that a star doesn’t have a defined way to follow or defined number of position changes. Today it changes its position in one way and the other day it would take some other way and change the position.
What can you infer about the position (value) a star (variable) takes?
Same variable can have different value in different situation
As Ramses says, a star can vary its position like this (go left) or like this (go right). So this means the star has many ways (meaning values it can take) and that its position is different in different cases.
