When i was in Bogota, i stayed with Martha and Hugo. Hugo is a mathematician. he asked me which area of mathematics i studied. I told him Abstract Algebra. Then he told me a funny story.

Many Colombian students are not great at Algebra (regular), and almost all the Algebra textbook in Colombia is written by a Cuban mathematician Aurelio Baldor with Islamic custom. So people are joking that he is a mathematical “terrorist” who drops math bombs . hahahaha ….
