#Is the distributive propriety an axiom?
26 messages · Page 1 of 1 (latest)
what exactly do you mean by this?
if you're asking about i.e. the peano axioms, it's that
if you're working in the foundations of mathematics, you might ask i.e. "what is a set?"
intuitively people had this notion that a set was just "a collection of objects"
but russel's paradox means you can't define a set like that
so like intuitively, the natural numbers definitely should exist
ZFC provides a framework (and says natural numbers exist)
it turns out that once you know natural numbers exist, you can construct the integers from the naturals, the rationals from the integers, the reals from the rationals etc.
so you only need to know that natural numbers exist
but this is more for foundational mathematics
if you don't work in foundational mathematics and for example you work with fields/rings
one of the axioms of a field/ring is the distributivity property
so distributivity is an axiom
also what exactly do you mean by "a geometric derivation for real numbers"?
At least it works with arithmetic (I think)
i mean that's not rigorous unfortunately
This is what I thought
So, even it has a "proof", but is not rigorous enough, right?
According to the Gödel's theorems, there's "infinite axioms", right? I've searched some stuff about it and some guys said that (at least as I've understood it) there are fields of math that there's "infinite axioms" and fields that not
Some of these "infinite axioms" have non-rigorous "proofs" like this one above? Because, for me, saying that a(b+c)=ab+ac is truth, memorize it and that's the end is completely different of saying "this proof, although it's not rigorous, give us an intuition of this fact". I like to accept facts when they are intuitive.
This is an intuition, but not a proof
Intuition can be dangerous
Here's a little example where intuition can counter truth
