Activity within 7 days: 8 New Members- 2 New Messages - New QuestionsDescriptionIf you like challenging math problems then you might consider joining this club. Problems are usually posted at least once a week. And if you think you have a solution to one you can post it. NOTE: To make it easier to know which problem people are working on please number the problem when you post it. And please take note: aspiring new members must be approved by a moderator or owner. This might take anything between minutes or two weeks, depending on who is online. So please be patient!
