Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

Okay, so I had a personal project for a long time that addressed the potential for an algebra that allowed for the multipicitive inverse of the additive identity.
In the context of the resulting non-associative algebra, 0/0=1, rather than 0.
For anyone wondering, the foundation goes as such: Ω0=1, Ωx=ΩΩ=Ω, x+Ω=Ω, Ω-Ω=Ω+Ω=0.
A fun consequence of this is the exponential function exp(x)=Σ((x^n)/n!) diverges at exp(Ω). Specifically you can reduce it to Σ(Ω), which when you try to evaluate it, you find that it evaluates to either 0 or Ω. This is particularly fitting, because e^x has a divergent limit at infinity. Specially, it approaches infinity when going towards the positive end and it approaches 0 when approaching the negative.
There's more cool things you can do with that, but I'll leave it there for now.
Interesting. I think it isn't unital either otherwise Ω=0.
0=Ω+Ω=Ω+ΩΩ=Ω(1+Ω)=ΩΩ=Ω
Someone else had the same observation, but it is unital. Keep in mind that it isn't associative; you can't pull out the Omega like that.
The definition I'm aware of for non associative algebras has them distributive by default, so I believe the chain of equations is valid.
