}I guess you've not read Kant. All mathematical propositions are

}synthetic apriori, too.
This is taking the question perhaps too literally. After Kant,
developments in non-Euclidean geometry made it clear that geometry was
not synthetic a priori in the way that Kant thought it was. It's
pretty clear, pace Matthew's support of analytic a posteriori, that
mathematical propositions are either synthetic or analytic a priori.
Now that further research has moved geometry up to the level of
analytic propositions, the search for synthetic a priori propositions
moves on. If anyone is really interested, there's an article by
Michael Friedman in the 1985 volume of Philosophical Review on "Kant
and Geometry" that discusses the synthetic/analytic distinction quite
well.
