@ASKASK Thanks! Is the dot symbol also a convention or just a typo? BTW this seems like an answer to my question so feel free to post it as such.

comment How do I convince someone that $1+1=2$ may not necessarily be true?
Note that while 1 + 1 = 2 can be false if you use different axioms, 1 + 1 = 2 is not itself an axiom. So using the Peano Axioms (which are usually implied unless otherwise stated), 1 + 1 = 2 can only be true since it necessarily follows from the axioms.

Here 'terminates' refers to the same kind of reals I was referring to as ending with 0000... right?

Yeah, in decimal base.

comment Refuting the Anti-Cantor Cranks
I think this actually shows that before applying Cantor's argument to any list, you need to make it at least base 4 and then use two numbers in the middle (such as 4 and 5 in base 10) to generate the anti-diagonal.

comment Refuting the Anti-Cantor Cranks
Would downvoters mind providing a proof that this argument is wrong instead? As far as I understand, Cantor's argument should work in any base, with any arbitrary infinite list of reals.

So this is why I was having so much trouble trying to figure out myself why it works...
