PEN Project

I Rajarshi Chatterjee am a staff member of the PEN project which aims at collection of problems in elementary number theory and giving their solutions.As of now, its pace has slowed down and it invites anyone interested to contribute.

There are no terms and conditions except that one can only post elementary problems from olympiads and of their own making and post correct solutions only.I invite all to contribute as much as they can.

If anyone interested to join us can also ask for that with their e-mail IDs and I will forward them to the others for approval.
