Sum of primes < n

  1. Jun 12, 2008 #1

    I have been searching the web for this subject to see if the formula I stumbled on
    is out there. This site came up often, so I registered.

    Working with tables of the known primes < n and sum of primes < n SumP(n), I was able to
    determine that SumP(n) ~ Pi(n^2). See


    Comments are welcome.
