Hello, I'm Serols. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Class (set theory)—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. Serols (talk) 17:52, 20 June 2022 (UTC)


 * They may have done it by mistake, although not as likely. They seem to have removed random pieces of content and replaced it with gibberish.
 * if you didn't mean to, don't worry, it's already been undone, just let the editor(s) who reverted your contributions know. Veryfactualedits (talk) 17:54, 20 June 2022 (UTC)
