Am I the only one that doesn’t care what the volumes at? if I can hear it and it isn’t too loud idc if its even, odd or ending in 5/0

Or if they expect that, go for a quaternion instead!

This is fun, I will do this from now on

You have the explanation, but more precisely: the set of definable real numbers is countable, because a mathematical definition can be encoded as a finite sequence of mathematical symbols (of which thereare only finitely many), and so there are only countably many definitions.

Hence most real numbers are undefinable.

By the way, there is a simple proof that all natural numbers are definable: if not, then there is a smallest undefinable number. But “the smallest undefinable natural number” would then be a definition of that number :)
