Hello, I'm PhantomTech. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Introduction to Calculus/Differentiation, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. PhantomTech (discuss • contribs) 23:53, 29 July 2022 (UTC)
