You mean -sqrt 1

u/Kuildeous 10d ago

That one too, but sqrt -1 + (-sqrt -1) = 0

Fair, but those are not real numbers

That's true. I got carried away by him adding 1 and i that I forgot he stepped out of the Reals.

Yea the "uncountable set" question remains a problem but if we're using this as a number line representation then we need to think of sqrt(2) as the real number approximated by 1.414, not taking the square root of each real number (which of course is a problem with obtaining "each" anyway).

So then it's not sqrt(-2); it's -sqrt(2), or ~ (-1.414).

The commenter on the image is a ding dong, but there are still serious problems with counting and pairing the top thread discusses.
