Are we or arent we using hard and fast rules ?


oh well onto the proof.
> An odd number must comply to _all_ of the following rules:

> 1. It must be an integer not exactly divisible by 2.
Well 1 when divided by 2  results in 0 remainder 1, so this proof 1.
> 2. It must be divisible by 2 with a remainder part of 1.
If I divide 1 by 2 I get 0 remainder 1, so this is proof 2.
> 3. It must be of the form 2n+1 for some integer n.
so (0 X 2) + 1 
#
So are we moving the discussion of proof from 1 is a odd number to 0 is
not a integer.
