you can because (1) defines N as a non-empty group

No
ah okay. Never mind then that comment wasn't directed towards you.

lol I'm pretty sure you can't define x to be a natural number if we're trying to build them from scratch.
x being a natural ofc
what do we define X to be?
yeah it's a first year of math superior studies i think. but it's not that complicated honestly. basically what he is asking is "how did we build the mathematical objects 1 and 0"
and the answer is easy:
because we needed them, digits are the building blocks of numbers then group of numbers build up into other groups and so on. If you want a full proof of real numbers and it's 10 properties then just check basics of linear algebra.
axiom to define natural number group is: 1)it contains 0
2)if it contains any x then it contains this x +1
so if it contains 0 then it contains 1
if it contains 1 then it contains 2
and so on...

so what axioms do we use to define natural numbers?
What is the simplest one?

Maths is bore ! i didn't like to study math how can tell answer of this question very difficult to me
well if you want to go with the naturals, of course everything is axiomatic: it 's a group whith the property "if it contains a natural number then it contains the next one"
if X belongs to N (natural numbers group) then X+1 belongs to N
1 and 0 being defined as in my previous post:
N={0,1,1+1=2,2+1=3,........}
the thing is the digits from 0 to 9 are just made up as they were needed at a time. so the building properties of the group is axiomatic and if you want to deny it, well you have to make up your own maths there
if X belongs to N (natural numbers group) then X+1 belongs to N

eh kinda. That was something similar my professor showed me but with Natural numbers since using real numbers is not allowed until you define them which requires much more proof.
I was kinda just going for the number 0.
0 has certain properties which we can accept as axioms.
1 has certain properties which we can accept as axioms.
0 = empty set
1 = {empty set}
2 = [empty set, 1}
etc...

in the real number corpse
the neutral is the real number with property
1.X=X.1=X where X is any real number and "." is the mulktipplication as defined in R
the zero is the real number with the property
0.X=X.0=0 where X is any real number and "." is the multiplication as defined in R
they are unique by definition (easy to prove)
Not sure it's a mathematical answer you wanted tought

I don't think this will get many replies.
ugh.... I thought the bitcoin community was filled with Mathematic fans.....
:/
No Mathematics fans here only miners.
no one likes math except for math teachers
I like Math. I just don't love it.
Indeed, Math is okay, but it's not like I think about it when I'm horny.

What are the simplest axioms we can use to describe 0 and 1 (before well-ordering etc....)?
You've got to be in it to win it.
