But at that point you are out of realm of arithmetics any way.
Comment on What do you think objectivity is, and what do you think of it?

1+1=2, except for when it’s not :)

The volume of a mixture cannot be described by a simple sum of the volume of its components. As such, this does not make the statement “1+1=2” false in this situation; it’s still true but irrelevant, there’s no “+” here on first place.
Additionally, let us suppose for a moment that the reasoning above is invalid. Even then, it’s still an objective matter - because then the truth value of “1+1=2” would vary depending on the object (are we dealing with apples, or liquid mixtures?), not on the subject (who’s mixing the liquids - you or me?).

It’s subjective as in: imagine a different society/species constructing a sense of reality and computation, based on liquid mixtures. Their basis of computation, their axiom is 1l of alcohol + 1l of water = 2l of mixture.
They meet us, and we exchange ideas.
They go: of course 1 + 1 = 2, look at our mixture. For fruits, apples and pears? That’s outside of normal arithmetics, it’s an exception. You have to correct for the non mixture nature, the answer will be larger than 2.
