Yes.
No. There are things mathematically called 'negative ' quantities.. If you talk about distances on a graph, we call movement to the right- positive , and movement to the left - negative . You needed to define what you mean when you are using the word distance. When Land Surveyors measure distances they frequently need to use the negative sign to indicate very clearly what is to be conveyed to the reader of their information, especially when they are doing surveying of levels and heights under bridges and in tunnels etc.

The absolute value is the distance form zero. It is always positive.
Absolute value is always positive. Absolute value is the distance away from zero. Ex: |-4| = 4 |4| = 4
diffrence will always be positive except when it is zero but is you speak of substraction operation it can be positive negative or zero
No. The absolute value refers to the distance between a number on the number line and zero. Because it measure the distanceto zero, the absolute value of a number is always positive. So, any integer that is positive will be identical to its absolute value.
No. An absolute value will always be positive, as it is a measurement of distance from zero on a number line.* * * * *Pedantically, not quite! It will always be non-negative: it can be 0.
