The coordinate axis reports from zero, but isn't that two zeros? + 0 and - 0?

Question

Mathematics

Will the expression be
0-0=-0 ?

If we take the coordinate axis

Then we have a reference point of zero .....
Is this correct?
You can't divide or multiply by zero, but you can add and subtract.
Therefore
+0-0=-0?
and not just a positive zero?
So there is a difference between positive and negative zero?
what is the difference between honey + 0 and minus 0 does it mean that zeros with different charges are not equal?
let's say we have a zero with a positive charge and a zero with a negative charge, are they not equal in this case?
Zero is not equal to minus zero? or equal?

Answer 1

Zero has no sign and is neither positive nor negative.
The zero sign appears in some implementations of machine arithmetic, but it has nothing to do with real zero from mathematics.
