In most civilizations where the number concept developed, the most complicatedContinue reading “From Numbers to “Pure” Math: Ancient Greece”

In my last post, I argued that a distinction needs to be made between calculation and math. But certainly these are related, because calculation is about numbers, and math uses a lot of numbers. So what exactly is the connection? Working from my own experience being trained to be a mathematician and educator, as wellContinue reading “Where Did Numbers Come From?”
