Hello, I'm Materialscientist. I noticed that you recently removed some content without 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; I restored the removed content. 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.

Please refrain from making test edits in Wikipedia pages, such as those you made to Algebraic fraction , even if you intend to fix them later. Your edits do not appear to be constructive and have been reverted. If you would like to experiment again, please use the sandbox. Thank you. Materialscientist (talk) 13:15, 17 August 2015 (UTC)
This is the discussion page for an IP user, identified by the user's IP address. Many IP addresses change periodically, and are often shared by several users. If you are an IP user, you may create an account or log in to avoid future confusion with other IP users. Registering also hides your IP address.
