For example, it implies that for 3 sets the symmetric difference is the set of elements in any of the 3 but not all 3. This is wrong since the symmetric difference for 3 sets includes the intersection of all 3 sets.\r\n\r\nThe link to the video is great, but I think the wording on the problem could be improved for clarity."},"comment":{"url":"https://api.github.com/repos/FreeCodeCamp/FreeCodeCamp/issues/comments/164913367","html_url":"https://github.com/FreeCodeCamp/FreeCodeCamp/issues/5308#issuecomment-164913367","issue_url":"https://api.github.com/repos/FreeCodeCamp/FreeCodeCamp/issues/5308","id":164913367,"user":{"login":"AlexWD","id":2994247,"avatar_url":"https://avatars.githubusercontent.com/u/2994247?v=3","gravatar_id":"","url":"https://api.github.com/users/AlexWD","html_url":"https://github.com/AlexWD","followers_url":"https://api.github.com/users/AlexWD/followers","following_url":"https://api.github.com/users/AlexWD/following{/other_user}","gists_url":"https://api.github.com/users/AlexWD/gists{/gist_id}","starred_url":"https://api.github.com/users/AlexWD/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AlexWD/subscriptions","organizations_url":"https://api.github.com/users/AlexWD/orgs","repos_url":"https://api.github.com/users/AlexWD/repos","events_url":"https://api.github.com/users/AlexWD/events{/privacy}","received_events_url":"https://api.github.com/users/AlexWD/received_events","type":"User","site_admin":false},"created_at":"2015-12-15T22:09:33Z","updated_at":"2015-12-15T22:09:33Z","body":"How about:\r\n\r\n    The symmetric difference of two sets is the set of elements which are in either of the sets and not in their intersection.\r\n\r\nIt's a little nit-picky but that's more clear imo."}}
