B Is there a symbol for "probably equals"?

@John Bartle you have been pursuing this notion for several posts. However it appears that there is no such symbol. Perhaps because one can’t use for anything other than what you want a shorthand for probably equals.

We have three categories already:
- things equal
- things we don’t know are equal
- things not equal

To which you want to add:
- things probably equal
- things probably not equal

To the list where maybe quantum computing would benefit but I have yet to see that and so offered the % over equals in the interim.

It’s an invention based on past equals symbolic conventions and I have no reference for it. I leave to future posters to come up with a probably not equals symbol.

We can all agree what it means for two expressions to be equal. Or not. But I don't think we can agree on what it even means to be "probably" equal. 95% chance of being equal? A 90% chance of being within 5%? And if we can't agree on what we are talking about, why do we need a symbol for it?

Yeah, I noticed. But in post #16 "I asked Hey does anyone know if there is a symbol for "A necessarily equals B"" It seems like this new question is relevant enough to my original post and needs that it would be on topic to ask. I don't see why this would be against the rules. I figure if no one wants to further engage then I'll stop posting. I guess that's acceptable forum etiquette?


I just test the waters to see what general options are available. I do the same thing with words when I look for synonyms. Even though most synonyms would practically work I still will look for that "special" synonym.

It wasn’t against the rules, I was worried that you were pursuing something that just doesn’t exist yet and maybe never will. We alll get stuck in this notion of there has to be something and if I search long enough I’ll find it.

Lol, so true.....:smile:

v_A = cat
v_A = v_B when v_B = cat or animal or feline or etc...
v_A = v_B if v_B = cat, animal, feline, etc...
v_A = v_B where v_B like cat or animal or feline or etc...
if v_B = cat, animal, feline, etc... then v_A = v_B
when v_B = cat or animal or feline or etc... then v_A = v_B
where v_B like cat or animal or feline or etc... then v_A = v_B

probability added before or after the compare with the if, where and when clauses.
 
Is there a symbol for "probably equals" ?

An example would be A probably equals B.
I was actually talking about this with a friend yesterday.

We were discussing about 0^0 and how it "probably" be 1. Even the maths implies that it would eventually be 1, but without an infinite number of equations it fails.
For instance 0^google would still be 0, because Google is still a countable number.
But when doing 0^0 , the closer you get to powering 0 by 0, the closer your answer comes to 1.

So if you do find a symbol tell me so I can apply it to 0^0 (probably)= 1

Do you mean "googol"?

I like how you phrase that in a question like it isn't obvious... I'm not trying to be rude but you clearly see it's a typo, you clearly know what I'm talking about... So is it really that worth it to nit pick an error that was autocorrect anyways?

It would have been better to just simply state that I made a typo, not ask me like I'm too stupid too see... Kind of insulting. I'm a grown man, if I make a typing error (on my phone God forbid) just tell me, you don't have to be cynical about it.

A lot of people, for the obvious reason, think that the number is spelled the same as the engine. I thought it was worth pointing it out.

No need to be overly sensitive here. All of us have experienced the case of using the wrong word from time to thyme and the spell checker misses or mangles it.

Recently my phone corrector had done that just as i sent a text, changing a misspelled word to a womans name in a text to my wife.

I pwned guy once who was certain it was spelled Google. He'd never known they were two different words.

The problem with the internet is we forget that we just dont know peoples ages, gender, accents, languages.... and consequently dont know what to take as a basis for conversation.
