Some people believe mathematics to be a very hard subject - particularly students in Thailand who noticed the woman on the cover of their textbook ‘Basic Mathematics’ was a porn star.
According to Laughspin the publishers, MuangThaiBook, harvested a picture of a pretty young woman reading a book labelled "mathematics" from a Google search.
The picture in question was of Japanese porn star Mana Aoki, and was taken from the movie Costume Play Working Girl.
“We will recall the problematic textbooks from every college that purchased them, and we will ship textbooks with new covers to them,” Said Dr. Chaipruek Serirak.
According to Rocketnews24, about 3000 of the textbooks have been distributed.
The UK's Metro reports that Aoki is one of Japan's top earning adult actresses.
