One step? ;-)

Perhaps you meant: if I'm standing at -1, the South pole,
and I move -1, one step backwards, what is my new location?

I guess that would depend on how large the world is.
If half a step gets me to the North pole, then a full
step gets me back to the South Pole.

But why are you taking steps, which are additive instead of
multiplicative?
