Normally we count from 0.
Zero plus this, Zero minus that... We take it for granted when we punch a number into a calculator that it's treating 0 as the origin.
So what happens when we treat Infinity as the origin instead?
When imagining Infinity within the context of the number line it's common to imagine positive and negative Infinities as two distinct points at each end of the number line.
Instead, try to think of them as the same point.
Like Zero, Infinity is non-polar.
With that in mind it's easy to make a perspective shift. By treating Infinity as the origin we can instead count from Infinity towards Zero. I call these Shadow numbers.
There isn't much use for Shadow Numbers today but I'm leaving this page here as a placeholder for future reference.
