Look at the titles of these books. Does it require any more explanation?
What In The Heck?!?! I mean come on Hot X Algebra Exposed?? These are actually math books designed to look like Cosmo. There are even sections on why guys like smart girls. I just roll my eyes. I know that there is a constant battle to get more girls interested in math and science but this is just pandering to them. Not only that, but why does everything have to border on vulgar? Or at the very least contain sex appeal? Shouldn't we be trying to get students (male or female) interested in a field because of the possibilities it will open for them and the way it will help them in school and life instead of trying to somehow sensationalize it with sex? It just kills me that we as a society have to stoop this low to get girls to study math. I can't imagine why our country can't compete with other nations in education anymore. Hmm...maybe they focus more on the subject and less on making a guy think about your "exposed X".
