Hello, I'm Donner60. I noticed that in this edit to Closed-form expression, you removed all the content without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, I restored the page's content. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Donner60 (talk) 01:38, 2 April 2018 (UTC)
