Has anyone here heard of the Piraha (or Hi'aiti'ihi as they call themselves), an Amazonian tribe that has no words for specific numbers? The closest they have are three words for relative amounts, roughly "few" "some" and "many". As a person who has struggled with math my whole life, I find this rather inspiring. Especially insofar as I have noticed that mathematics (along with other fields) has largely been developed by civilizations for the purposes of commerce. The Wikipedia article alone glosses over many other interesting details of their way of life.
