> not only American kids I doubt this is just Americans. Even limiting ourselves to adults from first world countries, I would estimate that: - Less than 50% can do an euclidean division without a calculator. - Less than 10% know the difference between mean and median. - Less than 2% could write a simple proof. > Now, average people have less arithmetic skills than Greeks from 2000 years ago. That's unfair: most people 2000 years ago couldn't even read. You're comparing the average joe with the top intellectuals of their time. I'm pretty certain that anybody with a decent scientific education today has knowledge that effectively subsumes or replaces everything the Greeks knew.
