I have a History and Philosophy of math course which covers everything from the beginning of math history, could anybody give me some IDEAS as to what topic I should write about?

I’m going to be doing my own research obviously, but I was just wondering if anybody has any interesting historical math concepts or ancient civilizations who used math.Thanks!

If you think I should be doing my own homework, don’t answer! I’m not using you for getting any school work done ha ha.
