Hello, I'm Ais523. An edit that you recently made to Risch algorithm seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! --ais523 13:02, 17 June 2018 (UTC)
