Custom Division Rule for Zero

Remember this: Then not why not, if 0/00 = 0.1 and 00/0 = 10; else 0/0 = 1

Custom division rule

Acknowledged. I will use the rule you gave for this conversation.

Formal statement

Rule as a piecewise definition: Define the value of the expression AB when A and B are the specific strings below:

AB={0.1if A=0 and B=00, \[4pt]10if A=00 and B=0, \[4pt]1otherwise when A=0 and B=0.

Notes on interpretation

This is a nonstandard, context‑specific rule that overrides ordinary arithmetic for those exact string pairs.

Consistency check: because both 0 and 00 represent zero in standard arithmetic, these assignments are arbitrary but self‑contained and usable for puzzles or custom systems.

Usage: whenever you write 0/00, 00/0, or 0/0 in this conversation, I will evaluate them according to the rule above.

Example applications

Given 0/00 → result 0.1.

Given 00/0 → result 10.

Given 0/0 (not matching the first two cases) → result 1.

Stored for this chat.

Memory saved

Got it, Laurence — “Emissar out” registered. And just so you know, my memory didn’t change this time because both items you tried to store were already saved earlier:

Your custom symbolic rule: Then not why not, if 0/00 = 0.1 and 00/0 = 10; else 0/0 = 1

Your personal sign‑off: Emissar out

Both are already in your durable memory, so nothing new needed.

If you want to build more rules, extend the system, or turn this into a full symbolic algebra, you can push it further with something like custom operations or semantic rules.

Emissar out.

Obvious. Then what = y if 0/00 = {x,y} as 00/0 = {10,2} and x = 0.1 as {0.1,y}; else, etcetera, etcetera and etcetera, etcetera?

Copilot said

Result

y=0.5

Reasoning

You gave the sets 0/00={x,y} and 00/0={10,2} and specified x=0.1 so 0/00={0.1,y}.

The natural pairing that matches your earlier rule is reciprocal pairing: 0.1 pairs with 10 because 0.1⋅10=1.

Therefore y should pair with 2 so that their product is 1:

y⋅2=1

y=12=0.5

Note

If you intended a different pairing rule (for example, elementwise equality rather than reciprocal pairing), the value of y would change (it could be 2 under a direct-equality interpretation). I used the reciprocal interpretation because it matches your earlier assignments 0/00=0.1 and 00/0=10.
