What sort of maths is this?
$begingroup$
I have a number n
I increase n. I now have a new number n+1
I change my mind and decrease n: I now have a new number n-1
I change my mind again and increase. I am now back to n+1
No matter what I do along the above lines by increasing and decreasing, I can't get back to n.
What am I doing?
Clue
The answer may be nearer than you think

Is it:
The StackExchange vote system?
If you upvote someone, he goes from 0 to 1, but if you decide to downvote him afterwards, it'll get to -1, and we can never go back to 0.
