Maybe women are simply not as interested in them as men. I'm sure there are areas where this is reversed. Seems fine to me.
That could easily be part of it. I am not trying to argue against this idea.
I went to college in middle-age. I am interested in the sciences, but I knew I did not have the math skills or ability to do well in science as a course of study. I went with an English concentration and an Education minor.
This is, or it seems to be and I could be mistaken, another "gender difference" that appears to have been more imposed than assumed. By that, I mean that women don't tell themselves they are bad at math, so much as they are told they are bad at math, by teachers and parents. (Those are generalizations on my part, and are not intended to be 100% accurate.)
The topic has been studied, however. When I was in public school, in the '60s and '70s, studies done showed that girls were steered away from maths, essentially made to feel math was a "guy thing." Remember the 1992 talking Barbie that said, "Math class is tough!"?
Researchers at the University of Wisconsin-Madison say that gender inequality is the cause of the “math gap” between boys and girls—not just girls sucking at math.
The study looked at countries in the World Economic Forum’s Gender Gap Index and found that girls score better at math in countries where there is more freedom, better education and financial opportunities for females. For example, girls in Iran, that beacon of women’s rights, scored low in the International Mathematical Olympiad—but in the U.S., girls are taking high school calculus at the same rate as boys. But don’t burn your “math is hard!” Barbie in a flaming pyre just yet. In American schools, boys are still considered to be more “mathematically gifted” than girls, meaning that your little sisters and nieces are still being discouraged at schools. From Fox News:
“There’s a gender stereotype that boys are better at math than girls are, and stereotypes die very hard,” [University of Wisconsin-Madison psychology professor Janet] Hyde told LiveScience. “Teachers and parents still believe that boys are better at math than girls are.”
The blog post was written by a woman, and her final comment regards the D+ she got in college math, and she muses she didn't know her bad grade was a result of gender stereotypes. She sounds...unconvinced, and a tad sarcastic.

But as mentioned, this is hardly a new idea. I've been hearing about it since the '70s, myself, and it could be even older than that.
While in college, I despaired a bit, because I knew I'd have to take a year of math, including the dreaded algebra I failed so miserably at in 7th grade and never tried again.
But in college, I took a 101 Logic class, in which it quickly dawned on me that logic is algebra, but using words instead of numeric equations. After passing that course with an A, I went on to pass my algebra and College Mathematics courses with a B in each.
It disturbs me a bit to consider I might have gone a different direction, had I this opportunity while I was still in public school.
