does this help at all?
Standard definitions and symbols:

A lot of this math is beyond my training. There are standard symbols used in math (and set theory), and they do not depend on your native language. If you could use those symbols, perhaps some of these math professors could then see clearly what you are trying to say.
Dear Don At Work,
First, thank you.
What I say is very simple and it does not depend on any particular representation of it.
In order to get it, please ask yourself a simple question:
How two opposites (abstract or not) can interact with each other without eliminating each other?
Please be aware that according to Classical Logic X AND X's negation is a contradiction, or in other words if X is definable, then X's negation cannot be found (and vice versa), otherwise we get a contradiction (no one of them can be found).
Since this is not the case, then Classical Logic is not sufficient enough to provide the answer.
You may claim that X OR X's negation enables to provide the answer.
In that case I agree with you, but first we have to understand what is OR.
Let X be True = T
Let X's negation be False = F
The truth table of OR is:
FF --> F
FT --> T
TF --> T
TT --> T
It can be reduced (without a loss of generality) to TT,TF (or TF).
What we get is invariant state (represented as TT) and variant state (represented as TF or FT).
So the principle that enables T and F to share the same universe without eliminating each other is based on invariant\variant complementation.
You may claim: but OR, AND, NOR, NAND, etc. … are all connectives of Classical Logic, so you have used Classical Logic in order to provide the answer.
My answer: Classical Logic cannot work if X and X's negation contradicting each other.
Any connective of Classical Logic can be used because of the invariant\variant complementation, and not vice versa.
Try to avoid the invariant\variant complementation and Classical Logic does not hold.
