11 yo tried to get out of doing his math homework on the grounds that the questions were, technically, valid answers. I explained that what he's really doing, and what most math is, is transforming quantities to a more useful form.
I'm including things like sets and truth values. I would have said formal objects rather than quantities, but then fewer parents would have understood.
