I mean, there are lots of ways that 2 + 2 = 5, but the fact that the numbers aren't precise is the simplest one for people to accept. There's very little point going into other examples if they can't accept the basic stuff.

And in vector math 2+2 = the inclusive range [0,4], depending on the relative angles

You're still assuming 2 is precise.

2 IS precise. 2 grams is not. 2 inches is not. But 2 itself, the product of no unit and no context other than itself is precise 65,000,000 is precise. 65,000,000 years is extremely imprecise.

2 isn't precise. 2.0... is. It is commonly accepted that 2 is precise, but that's a convention and not universal.

It's universal to any case in which there is no other context to the 2 than its own inherent 2ness, barring any post hoc shoehorned context in which case it ceases to be a contextless 2 anyway

By definition, there cannot be such a "case", a "case" means you're talking about real things that are actually happening that someone cares about for some actual reason

The case being the discussion and conceptualization thereof. I mean you might be under the impression that thoughts aren't real because you've never actually had one but...

Well, that's not a case, is it Talking about numbers in the abstract is fun but they don't actually exist, they're like Pokemon

This definition of existence implies that only matter exists. Information is not matter. Does this tweet exist?

Would you work in a skyscraper designed by someone who thinks 2 + 2 = 5?
