Hello, I'm DVdm. Your recent edit to Velocity-addition formula appears to have added incorrect information, so I removed it for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. DVdm (talk) 16:02, 4 March 2020 (UTC)

Hello, I'm LuK3. I noticed that you recently removed content from Crescent School without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. --   LuK3      (Talk)   21:49, 29 April 2020 (UTC)
