I am a grade 12 student, and for this semester, I am interested in doing a math research paper instead of a science one. I've looked up the internet regarding the different topics I can tackle on, but I'm still unsure of which topic to finalize with, because most of them are only taught in college. So far, I have been reading about Hadamard Matrices and their applications and it interests me, because I'm a big fan of algebra. But there is still that sense of doubt in me if I don't get anything. Any suggestions regarding about what can be researched about Hadamard Matrices will be useful, other topics may also do. Thank you.
