That sounds to more like playing with math than describing anything that exists.
I mean, they *could* exist, but the only evidence is in messing with mathematical symbols.
At some point, math as we know it could and may have already stumbled badly at the quantum level, just as Newton's physics eventually failed. Because it doesn't exist outside the mind.
Or perhaps math really is "real," but only up to a certain point.
I speak as someone who flunked calculus after doing pretty well up till then.
