Different sites have differing quality standards. A question can be a bad fit for multiple sites, even when an oversimplification of quality standards would lead to an apparent paradox.
Not all questions have a home on Stack Exchange.
mathsproblems.SE
is a solution? I don't think it is, and neither is throwing good questions out of the whole of SE.

Green is not blue. Neither is it yellow. It's just green. The fact that it is not blue does not require that it be yellow, nor vice versa.
Sometimes there are shades of green that are hard to separate from shades of blue or of yellow, and that's when we have a discussion about what we mostly see it as.
You are basing your argument on a false dichotomy, when in fact there are (at least) three options, and (at least) one of them is that the question is off-topic for both sites.
Sometimes it's hard to tell whether something is too mathy for PSE or too puzzly for MSE, and consensus is developed. Often, that consensus is on one or the other, and occasionally both, but also quote often it is neither.
That's not a paradox. It depends on the question itself. Ideally, only one of the two close reasons given will apply to any particular question. If not, you can just bring it up on one of the meta sites and we'll talk to the Math.SE mods about which site it would be allowed on.
Actually, we find ourselves more often allowing questions on both sites - several questions are cross-site duplicates. I don't think I've ever seen any case where the same question was closed on both sites for opposite reasons.
