I don't think math is an Intuitive pursuit at all. Math isn't really abstract -- at least not in the Intuitive sense. Contrarily, it's detail-oriented factual logic and highly systematic. Math is problem solving concerned with finding a definite answer -- very ISTP- or ISTJ-ish if you ask me.
The INTP and INTJ would be more comfortable with flawed logic, because N is open to fanciful rather than systematic thinking. Hence, contrary to popular belief, the INTP and INTJ are not nitpicking types.
Let's review that the N isn't about intelligence, it's about creative thinking. Math is quite the opposite way of thinking.
I haven't read the whole discussion but when I read comments like this, I must say that I disagree. Mathematical logic can be very creative and inventive, artistic even. Math is not just random numbers and solving problems with the help of boring formulas that you don't even understand anything about, even though math is sadly often taught like that in schools.
Btw, I suggest that everyone who thinks that math is boring and uncreative read this:

I am an INFx and I used to think that I'm an INFP but then I started studying theoretical math as my minor at a university, and as I'm often thinking about logical problems now, I cannot relate to the descriptions of INFPs any more, as most of the descriptions say that INFPs dislike logic and tend not to be very good at it. So I can't think of myself as an INFP any more, not now that I have discovered the world of math, not when according to the "rules" I should detest logic.
Calculating is fun but that's not the part about math (I accidentally wrote "magic" at first! lol) that I love. The part that I love is thinking deeply and philosophically about things like infinity and limits. To me, there's a whole different universe hidden in the world of math, a universe that we humans can only vaguely understand. It's fascinating.
I don't think that I'm very naturally talented at math... at least the online I tests that I have taken have indicated that I have an IQ that is just a little above average. But still, I have done quite well in my studies. I guess I have enough talent in any case and, combined with it, a lot of fascination and imagination, the latter being what really makes me "good" at math.
