Whenever any number (say x) is subtracted from itself, the result is zero (0). (Difference means that subtraction is performed)

Perhaps the difference of 9 and minus 9?

Ah, there we go with semantics!

the difference of 9 & -9 would be 9 - (-9), namely

the difference of 9 & NEGATIVE 9, which is 18.

But that's not what was requested, methinks.
