I'm not very proficient with math, but Ive managed to make my way to problem 7 of Project Euler using python. I have to now find the 10,001st prime number. I'm reading about Eucilid's theorem. But I'm afraid I do not understand enough about mathematical notation to understand the theorem.
What do the numbers in the p=p1,p2,p3 expression on this page (http://en.wikipedia.org/wiki/Euclid%27s_theorem#Euclid.27s_proof) mean? Is p the prime number? and the 1,2,3,4 are just counting the position?
Thanks in advance for your help.
