Hello, I'm Johnuniq. An edit that you recently made to Calculus 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! Johnuniq (talk) 00:49, 20 September 2018 (UTC)
