Hello. This is a message to let you know that one or more of your recent contributions, such as the edit you made to Dimension (vector space), did not appear constructive and have been reverted. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. Thank you. — Mikehawk10 (talk) 06:13, 27 May 2021 (UTC)
