is this proof of 1>0 in an ordered field correct?

139 Views Asked by At

As I do not know what to write here, I write only that I tried to prove that $1>0$ using the ordered field axioms (Ordered Field Axioms). I simplified what the site said for shortness only.

Try

Axioms and definitions used

Addition and multiplication

1b) $x+y=y+x$

1c) $x+0=x$

1d) $x+(-x)=0$

2c) $1x=x$ and $1\neq 0$

2e) $x(y+z)=xy+xz$

Inequalities

3a) only one holds: $x=y$ or $x<y$ or $y<x$

3b) if $x<y$ and $y<z$, then $x<z$

3c) if $x<y$, then $x+z<y+z$

3d) if $x<y$ and $0<z$, then $xz < yz$

Definition of greater than

D1) iff $x>y$, then $y<x$

Of that $0x=0$

As logic tell us:

$1x+(-1x)=1x+(-1x)$

$1x+(-1x)=0$ (by 1d)

$x(1+(-1))=0$ (by 2e)

$0x=0$ (by 1d)

which we'll recall by L1.

Of that $x\times -1=-x$

Logic says:

$0+(-x)=0+(-x)$

$0+(-x)=0x+(-x)$ (by L1)

$0+(-x)=0x+(-1x)$ (by 2c)

$0+(-x)=x(0+(-1))$ (by 2e)

$-x=x\times -1$ (by 1c)

which we'll call L2

Of that 1>0

If $1=0$, then we contradict the axiom 2c, therefore either 1 is less than 0 or 0 is less than 1 (3a).

As an assumption, let:

$1<0$

$1+(-1)<0+(-1)$ (by 3c)

$0<-1$ (by 1c and 1d)

As 0 is less than -1 (3d):

$1\times -1<0\times -1$

$-1<0$ (by L1 and L2)

$-1+1<0+1$ (by 3c)

$1+(-1)<1$ (by 1c and 1b)

$0<1$ (by 1d)

which contradicts our assumption that $1<0$. As 1 is not less than 0 nor it is equal to 0, then 0 is less than 1, i.e., (D1) $1>0$.

Questions

Is the proof correct? And did I show/write too much? Because I think I did.
