an example of absence is the 3

The first Peano Axiom states that 0 is a natural number, next these axioms define a function S(x), that takes x and outputs the successor of x
You start at 0, do S(0) and call that 1, then S(1) and call that 2, then by induction u have the natural numbers

Good boy! Any day now, you'll be a scientist!

0 is 'placeholder value'

All maths need share a unified 'we all agree that we don't want a 0 out of our equations, but everything else we can bicker/argue over'.

>hurr having 0 apples is an amount of apple

This is what mathematicians actually believe

The entire field has been on eternal suicide watch since Godel proved all math is a house of cards

Zero is absence of a number defined as a number.
