>>14352913Zero can be implemented super easily using just natural numbers. Define integers as pairs of natural numbers (x,y) which you can interpret as
x = person A's net worth
y = person B's net worth
Equality of integers is defined as
(x1,y1) = (x2,y2) if there exists a natural number n such that
x1 = x2+n and y1 = y2+n
or
x2 = x1+n and y2 = y1+n.
The pair (x,y) then simply describes who is richer and by how much. Addition is defined component-wise and represents change in net worth of both. Zero is an integer of the form (x,x), i.e. both A and B have the same amount of money. This is clearly a neutral element with respect to addition since giving the same amount of money to both doesn't change the relative wealth. There you go, a definition of zero without any schizo rambling about "absence of numbers" or "nothingness".
