A person can know the integral sign and know vaguely that it means "the area under a curve" without actually knowing calculus. Understanding the semantics of a term or symbol and being familiar with its referent are very different things. This is universally accepted and not controversial at all. If you'd like to continue arguing your point, I'd ask you to provide even a modicum of evidence. In terms of what you're "stating (as a fact)," I can tell you with absolute certainty that you're wrong. Many high schools do not teach set theory and, among those that do, many - mine included - don't refer to this operation as the Cartesian product. It is simply "the product of A x B."
