Christine - Crest of the Peacock introduction reflection

I was surprised to read how much different cultures interacted and likely shared Mathematical knowledge. It is interesting to me to read about where we get certain words and by extension the roots of mathematical knowledge. I did not know that the Arabs should be credited with the production and teaching of a substantial amount of mathematical learning. I am reminded again of the prevalence of the Euro-centric narrative of history and how my education neglected to teach the many developments in cultures outside of Europe. The transfer of technology, ideas and mathematical knowledge happened between many cultures. I also found it interesting to read about how place value was discovered independently at least four times; it fascinates me that humans in different parts of the world independently make the same discoveries!
